Transmission Characteristics
Compliance
The transmission characteristics for the North American and Latin American variants comply with:
ANSI/EIA/TIA 464-C 'Requirements for Private Branch Exchange (PBX) Switching Equipment'.
TIA-912 'Voice Ga teway Transmission Req uirements'.
The transmission characteristics for the United Kingdom variants comply with:
ETSI ES 202 020 'Harmonized Pan-European/North American loss and level plan for voice gateways to IP based networks'.
Mitel Networks digital telephones meet the requirements of:
ANSI/TIA/EIA-810-A 'Transmission Requirements for Narrowband Voice over IP and Voice over PCM Digital Wireline Telephones'.
Loss and Level Matrices
Requirements Specifications
Each country has stipulated requirements concerning acceptable transmission performance for telephone systems. The loss plan matrices provide the correct electrical losses in decibels (dB) for each connection to meet the specified requirement.
Loss plans have a direct effect on the acoustic levels provided at the set. Part of meeting the requirements is to identify the reference set requirements for all standard and proprietary sets to be used in each country. It is generally desirable to achieve the same relative loudness levels for all standard and proprietary telephones for a specified loss plan, taking into account loop lengths, transmission format (analog or digital), different transducers in use, line/trunk impedances, and terminating impedances.

Implementation
In the loss plans, positive values are losses and negative values are gains. The losses are shown in one direction only (outgoing, from the specified port type); the reverse path loss can be found by using a second look up (e.g. In North America, OPS to WAN is a -3dB gain and WAN to OPS is a 9dB loss).
Note: Mitel Networks digital telephones meet the following ITU-T recommended loudness rating: - Send Loudness Rating (SLR) 8 dB - Receive Loudness Rating (RLR) 2 dB.
In interpreting loss plans, refer to the following legend:

Overview
iONS ONS iOPS OPS iACO iACOs ACO ACOs DCO ATT
Networked MITEL Systems
A network of Mitel Networks systems consists of two or more systems, each referred to as a network element.
By using OPS Manager, you can manage a network of Mitel Networks systems from a single centralized station.
Terminology
Network: a group of systems interconnected through DPNSS.
Network Element: a system that is a member of a network.
Cluster: a group of MITEL or Mitel Networks systems interconnected through DPNSS. All systems in a Cluster share the same primary node identifier.
Cluster Element: a single MITEL or Mitel Networks system which is a member of a cluster.
Portable Directory Number (PDN): a call processing feature available in a cluster of systems. This feature allows you to move a user’s telephone directory number to any extension in the network (i.e., you can move a user’s telephone directory number to an extension on any other system in the cluster and allow the user to retain the same directory number).
Advantages of a Network
A network of telephone systems is a highly functional communications system that provides a greater line size than a single system. A MITEL or Mitel Networks systems network
Acts as a highly functional, virtual system for both local and wide area applications

Can be customized and sized to meet long term growth requirements
Can grow to a theoretical unlimited line size
Provides enhanced MSDN network feature functionality
Has an extremely effective digital/analog networking capability
Can be fiber-distributed and workgroup focused
Is standards-based and open to Computer Telephony Integration (CTI) development.
Each 3300 ICP network element will support up to 700 lines or up to 100 ACD agents. Two sizes of 3300 Controller are available. These units will support up to 250 IP telephones or 700 IP telephones.
Network elements can be geographically dispersed providing a high level of security to those organizations who maintain critical operations that might be interrupted due to some disastrous consequence. The element dispersal and the fiber optic connectivity of the nodes making up an element allow the terminating nodes to be located near the terminal devices, and they allow for savings in copper distribution cables and their associated protective devices.
Customers requiring ISDN or other broadband network connectivity can switch various voice, data, and video services to both the enterprise and desktop by utilizing other manufacturers equipment together with MITEL and Mitel Networks systems.
As the functionality, reliability, geographical coverage, and price points of virtual private networking (VPN) services improv e, greate r pres su re will be placed on the private networ k. This trend will continue through the evolution of ISDN services. Network customers will be able to select products that can interface with a combination of products and services. For example, a typical customer may choose to use MITEL SUPERSWITCH Digital Network (MSDN) between major centers and VPN between smaller or more remote locations.
Selecting a Suitable Configuration
When building a network, the final design should provide the most effective communications at the lowest cost (impacted only by business and geographical constraints). Additions to existing networks, although complicated by what is already in place, should reflect the configuration design concepts.
Network Configurations
A network can consist of all MITEL and Mitel Networks systems or combinations of MITEL and Mitel Networks products and systems from other vendors. This combination can also be a mixture of various smart (digital systems) and dumb (electronic and electromechanical) systems. To have full MSDN functionality, all the systems in a MITEL or Mitel Networks MSDN/DPNSS North American network must be SX-2000 systems or Mitel Networks 3300 Integrated Communications Platforms.
Note: In this section, the term system describes a MITEL or Mitel Networks system or another vendor's system serving normally as a hub switch.

There are three basic network configurations:
linear network
non-linear network
combination network.
Linear Network
A linear network is a network in which a number of systems are strung in a line. Networks of this type are typically used by railroads. An advantage of the linear network is that the design is simple. Some disadvantages are that as large numbers of systems are added, dialing can become complex with a tandem connection involved at each intermediate system in the connection; also, if all connections are routed through each intermediate system, a single facility system failure could seriously impact network operation.
Non-Linear Network
A non-linear network is a network in which every system has direct connections to every other system. This configuration has the advantage of a minimum of systems involved in each tandem call connection. Also, alternate routing can be used in cases where inter-switch facilities are busy or disabled. The disadvantage is the increased trunking requirements.
Combination Network
A combination network is a network that is a combination of both linear and non-linear networks. The combination network applies to most large network configurations. Maximum utilization is made of the advantages of both while minimizing the disadvantages. This configuration evolves into the following mesh, star, double star, and hierarchical star configurations used in more complex networks:
The mesh network is one in which each and every system is connected by trunks to each and every other system. Mesh networks are trunk intensive and are used when there are comparatively high traffic levels between systems and the geographical or economical conditions allow the expensive trunking required.
The star network utilizes an intervening system called a tandem switch. Each and every system is connected via a single tandem switch. Star configurations are normally applied when traffic levels between systems are comparatively low.
The double star network includes single star sub-networks that are connected via higher order tandem switches. The factor that leads to star and multiple star network configura­tions is network complexity in the trunking outlets (and inlets) of a system in a full mesh. For example, the typical mesh network requires that each of the five systems be minimally equipped with four trunk groups or a total of 10 trunk groups reserved for inter-network traffic. In practice, most large networks are a compromise between mesh and star configurations.
The hierarchical star network has evolved to eliminate confusion. That is, a systematic network was developed that reduces the trunk group outlets (and inlets) of a system, permits the handling of high traffic intensities where necessary, and allows for overflow and a means of restoration.

Page 35

A hierarchical network provides levels of importance to the systems making up the network. Call traffic restrictions can be placed on traffic flow based on the designated level of importance. For example, in the illustrated hierarchical star network, there are three hierarchical levels of systems. The smallest symbols in the diagram have been marked with a "C" to indicate the lowest level. Note the restrictions (or rules) of traffic flow. As the figure is drawn, traffic from C8 bound for C9 would have to flow through system B2. Likewise, traffic from system B2 to B3 would have to flow through system A1. Carrying the concept somewhat further, traffic from any "A" system to any "B" system would have to be routed through an "A" system.
The high-usage route is the next consideration. For instance, if we found that there was high traffic intensity between B4 and B5 trunks, a switch gear might be saved by establishing a high-usage route between the two systems. We could call the high-usage route a high traveled shortcut.
High-usage routes could be established between any pair of systems in the network if traffic intensities and distances involved proved this strategy economical. When high-usage routes are established, traffic between the systems involved is first offered to the high-usage route and overflow when the route is busy or unavailable. If routing is through the highest level in the hierarchy, we call this route the final route. Hierarchical Network shows traffic routed between systems B4 and B5 via system A2 (the final route in this case).
Cluster Network Configurations
A cluster network is composed of two or more Mitel Networks systems.
A typical cluster network can function independently or as part of a larger network or networks. Cluster elements are categorized as follows:
Main element
Satellite element
Hub element
Remote main element
Remote satellite element
Remote hub element.
In the Typical Distribution of Network Elements illustration, the hub element is connected to both the Public Switched Telephone Network (PSTN) with both local exchange (LEC) and inter-exchange carrier (IXC) connections. It also serves as the gateway to the remote network. The main element has connections to the local exchange carrier (LEC) and the satellite element has no PSTN trunking. Each element is connected to every other element with MSDN/DPNSS to minimize multiple tandem connections.
Network Element Relationship shows the relationship between different types of network elements.

Main Element
Main Elements can perform the following functions:
Originate and receive calls
Serve as intermediate switches in which they can function as tandem points for receiving and passing calls and information
Serve as terminating switches for most outside world trunking such as Central Office (CO), common carrier trunking, and tie trunks from the remote cluster network and/or other networks (note that the hub supports applications requiring tandeming capabilities)
Support centralized attendants, ACD, and centralized voice mail.
Note: Each cluster network requires a minimum of one main element terminating all outside world trunking that supports access transparency.
Satellite Element
Satellite Elements can perform the following functions:
Originate and receive calls
Serve as intermediate switches in which they can function as tandem points for receiving and passing calls and information.
Notes:
1. Special application trunking can be terminated on a node within this switch.
2. Each network supports up to nine satellites with a minimum of one main or hub
element for a maximum of ten elements. For Mitel Networks 3300 Software Release
3.0, physical restraints will limit this to 8 physical connections. XNET will allow further connections through amortisation of calls onto a common connection through the PSTN, i.e. traffic to multiple nodes could be carried through common physical links.
3. Satellite elements do not support centralized attendants, centralized voice mail, or ACD.
Hub Element
Hub Elements can perform the following functions:
Provide extensive trunking if applications such as remote network, PSTN, LEC or IXC are to be located on a single element
Serve as intermediate switches in which they can function as tandem points for receiving and passing calls and information between other cluster elements and the remote network, other networks as the PSTN (LEC and/or IXC), or other private networks
Originate and receive calls
Provide a centralized voice mail connection point
Provide centralized attendants and/or ACD services (note that applications can support some lines, but the major function is trunking).

System Distribution
Campus or Contiguous Applications
These applications involve placing cluster elements in a single campus or contiguous location. Normally, all of the real estate parcels are adjacent to or touch each other. All inter-element transmission facilities are the responsibility of the customer (not the telephone company).
Note: The recommendations for campus environments apply to multi-element cluster applications within a single building.
Provide more lines, trunks, and/or digital stations than are provided by a single system
Overcome electrical/fiber optic distance limitations
Disperse equipment minimizing total outages in the event of cable cuts or power failures.
Networks used in campus environments normally have two characteristics. First, customer-owned facilities (such as copper, fiber, and microwave) are used to provide the network transmission medium. Second, the geographical areas served by the network nodes are normally contiguous.
Take advantage of the following factors when designing a campus environment:
Identify communities of interest. Where possible, meet the telephone needs of a commu­nity of interest with a single network system node. This approach keeps calling patterns within the node requiring fewer trunk facilities to connect to other system nodes.
T ake advantage of existing or planned fiber optic cable. When the fiber distances are short enough, DSU nodes from each of the network systems can be centralized. When distances are too long for this type of configuration, fiber optic multiplexers can be used to provide DS-1 (T1) or CEPT facilities.
Look for opportunities to coordinate telephone and data services, and operations. Explore these opportunities carefully and, when possible, present and implement integrated solutions.
Remote Networking
The cluster can be installed with some or all of the cluster elements remotely dispersed. When designing a remote network involving all elements or cluster elements and other network systems, the information contained in this section applies. When designing a remote network involving mixed networks, cluster elements and other systems, the cluster should be designed as an entity, and then the connections to the other network systems should be considered.
Note: A cluster can be applied within a locality, across local, state and international boundaries.
Network Transmission Guidelines
A network consists of three parts:
1. Dedicated transmission facilities (tie trunks)
2. Exchange facilities (such as FX, Sprint/MCI/AT&T, and local exchange DDD/DID)
Release 3.2 2
Page 38

300 ICP Hardware User Guide

3. Switching equipment (such as a MITEL or Mitel Networks system).
Quality and Performance Guidelines are Required
Since the quality and stated performance characteristics of dedicated transmission and exchange facilities are most often controlled by common carriers, the number of creative or complex arrangements utilizing a combination of these three elements requires guidelines to ensure proper operation in the field. Off-net calling in a private network, multi-tandem on-net calling, and RADs are capabilities for which transmission guidelines are also required.
Maximize the Use of Digital Facilities
You can minimize transmission problems by using digital facilities. Use digital facilities when connecting the system nodes together and when connecting Local Exchange (LEC) and Inter-Exchange (IXC) carriers to the system nodes.
Private Network Calling
Off-Net Calling
Calls which originate in a private tandem network and extend through the public switched or other networks for completion are commonly called off-net calls. A frequent application of off-net calling occurs when long distance (LD) trunks are hubbed on one network switch and accessed through this hub switch by other (satellite) switches in the private, tandem networks. A second application involves the use of ARS routing over tie-trunks tandeming through multiple systems to complete off-net calls. Finally, switches can provide for off-net calling automatically at a distant network system location. These applications must be examined carefully prior to implementation to assure business operation compliance, transmission integrity, and documented economic savings.
Off-Net Trunks - The Public Switched Network (PSTN) trunks carry off-net traffic. In some cases calls may be carried as far as possible on-net and then be routed to off-net trunks. In other cases the call may access the public network at the closest system from which the call originated.
Off-Network Routing - The routing method to the public network depends on ARS and how the routing patterns are administered at each system involved in the connection. Calls that utilize the customer’s private tandem network and DDD network are commonly called off-net calling, double-tandeming, or tail-end-hop-off. A frequent application of off-net calling occurs when a customer concentrates WA TS lines in a system tandem switch which serves as a hub for these services with access via satellite systems. A second application involves the use of ARS routing over tie lines tandeming through multiple systems to complete off-net calls. Finally, the system can provide off-net calling automatically at a distant hub location.
Off-net trunks and off-network routing each offer economic and transmission quality compromises. In certain situations, transmission is satisfactory although there are times when the complexity of tandem switching, the quality of the trunks, and the common carrier involved, do not allow for successful transmission. Care must be taken in network design to identify potential transmission problem areas.

The three types of off-network routing methods are defined as follows:
1. Tail-End-Hop-Off (TEHO) routes an off-net call through the private network and hops off at the tandem switch closest to the destination of the call. As an example, a tandem switch in Atlanta which is connected to New Y ork originates a call to Philadelphia. The call is first routed on-net over the inter-tandem trunks between Atlanta and New York and then hops off on the FX trunk to Philadelphia.
2. Head-End-Hop-Off (HEHO) routes an off-net call to the closest tandem switch from where the call originated. As an example, a private system in New York originates a call to Dallas. The call tandems to an on-net system in Washington, D.C., and hops off using WATS to complete the call.
3. Best-End-Hop-Off (BEHO) routes off-net calls using the most economical facility and de­parture point within the private network. The call may hop off the private network at the originating, intermediate, or terminating tandem switch depending on how the routing patterns are administered.
Tandem and On-Network Calling
To minimize network management problems where there are more than three systems in a network, consult MITEL. For networks in North America contact MITEL Dallas Systems Engineering. For networks in the UK, contact the MITEL Technical Advice Center.
The following factors must be taken into consideration with respect to tandem and on-network calling:
Engineering Constraints - The availability of access codes and ARS routes at each network system and the digit outpulsing limit are engineering constraints. With careful engineering, you can design networks to include a considerable number of system nodes. Ideally, networks should be in a non-linear configuration.
General Network Data - A network consists of tandem switches that accept and pass call traffic, inter-switch tie-trunks and transmission facilities that connect the tandem switches, and access or bypass access tie-trunks from a tandem switch to another tandem or end switch.
Simple Networks - Simple networks are normally designed as symmetrical networks. The characteristics of a symmetrical network are tandem switches are of an equal level, all routes (trunk groups) are high usage, and circular call routing is prevented.
Complex Networks - Complex networks can be configured hierarchically for call routing. The characteristics of a hierarchical network are each tandem switch has an assigned level (upper and lower), each lower level system connects to an upper level system, upper level systems are completely interconnected, and there is a routing plan that prevents circular call routing.
Hierarchical Ranking - The hierarchical ranking allows an orderly routing of on-net access calls. The switching portion of the network is represented by the upper-level and lower-level tandem switches connected by inter-switch tie-trunks. The tandem switches can accept voice/data calls from any connected point and pass the calls to another connected point. The upper-level systems have a large amount of call traffic and the lower-level systems normally have small amounts of call traffic. Lower-level systems can be administered to
Release 3.2 3

300 ICP Hardware User Guide
3
overflow to upper-level systems, in most cases. Calls from upper-level systems do not overflow to lower-level systems because of the large volume of traffic.
Network Trunks (MSDN, Non-MSDN)
The tie-trunks that connect the systems within the private network are named according to function. That is, names like inter-tandem/inter-machine, access, and by-pass access denote function (type of routing) rather than hardware differences. The off-net trunks that provide access to Direct Distance Dialing (DDD), Foreign Exchange (FX), or Inter-exchange Carrier (IXC) are used by ARS to complete calls to the destination. IXC trunks provide access to Other Common Carrier (OCC) facilities. An off-net call may be carried by on-net trunks part way to its final destination before accessing off-net facilities to complete the call.
Inter-tandem/Inter-machine Tie-trunks - As its name implies, an inter-tandem tie-trunk interconnects to tandem switches. It can be one-way incoming, one-way outgoing, or two-way . Inter-tandem tie-trunks are further classified as primary high-usage, intermediate high-usage, or final, depending on the routing of calls and overflow routing of calls. The complexity of network, customer requirements, and economic factors determine trunk type and classification.
On-Network Routing - The overflow routing characteristics for inter-tandem tie-trunks are as follows:
Primary High-Usage (PHU) Inter-tandem Tie-trunks - These trunks serve first-choice traffic only. They do not receive any overflow traffic, but may overflow to intermediate or final trunk groups. They are designed to overflow at a present economic load level (see figure).
Intermediate High-Usage (IHU) Inter-tandem Tie -trunks - These trunks serve first-choice and second-choice traffic and receive overflow traffic from primary high-usage trunk groups. Like PHU trunks, these trunks overflow at a preset economic load level. They direct any overflow traffic to final trunk groups.
Final Inter-tandem Tie-trunks - These trunks receive overflow traffic from primary and intermediate high-usage trunk groups, but do not overflow to any other trunk group. These trunks block calls when all trunks are busy. When a call is blocked, the caller receives busy or intercept tone, or is placed in queue, depending on how the trunk is administered.
Overflow Routing - In the inter-tandem Tie-trunk usage (overflow routing) example, a call originating in Los Angeles would, as a first choice, be routed directly from Los Angeles to Atlanta over the (A) primary high-usage trunks. If busy, the second-choice routing would be to New York over the (B) intermediate high-usage trunk and from New Y ork to Atlanta via the (C) final trunks. If the (B) intermediate high-usage trunks connecting Los Angeles to New Y ork were busy, the final route (C) from Los Angeles to Chicago, Chicago to New York, New York to Atlanta would be used. The fourth choice, if the final route was busy, would be to route the Los Angeles caller to busy tone.
Direct Inward System Access (DISA)
DISA is designed to allow local calling area access to a customer's system and its networking capabilities. Take care when supporting long distance inward access, particularly 800 type INWA TS, via DISA for calls that could terminate in OUTWATS or DDD trunks in another distant point.
2 Release 3.2
Page 41
Specification
s

The primary problem is the uncertainty of the normal loss in the inward WA TS connection, which may not allow users to break dial tone from their DTMF pads.
Even if successful connection has been made, the total amount of loss when connecting INWA TS trunks to an OUTWATS trunk can be such that the user is not likely to hear the called party. The offering of WATS service, inward and outward, further complicates the problem.
These positions are consistent with common carrier transmission practices. It is very important to appreciate the capabilities and limitations of network configurations. Consultation with various common carriers is a required part of network selling and implementation. Any applications of off-net tandem dialing, built-up on-net calling, or remote DISA should be carefully reviewed by local systems engineering prior to any formal customer proposal.
Survivability
Survivability requires that all network operations would not be lost due to the failure of one or more, but not all, network elements. Network applications provide a much higher degree of survivability than a single system solution because networks are modular in design. Customer requirements and economics dictate the level of survivability for the network and the individual network elements.
Different Configurations Provide Different Levels of Survivability
Choose one of the following configurations to provide the required level of survivability:
Linear configuration - failure of a single element disrupts inter-network calls between some of the elements
Star configuration - failure of the hub element disrupts inter-network calls between all the elements
Mesh configuration - failure of one element only affects the subscribers on that element.
Maximize the Survivability of Critical Elements
Any cluster is only as good as its critical element. It is important that you identify critical elements and reinforce their survivability.
To maximize element survivability:
When possible, facilities for local exchange and common carrier trunking should come from more than one direction. Ideally, as a minimum, entrance facilities from more than one telephone company distribution cable system would be available.
Equipment should be located in secure, dry, storm hardened building locations. Each system node should have some central office trunking, which can be backed up with cellular facilities to bypass the local CO and/or cable plant.
Survivability of Local Exchange and Common Carrier Trunks Facilities
If possible, locate local exchange and common carrier trunks on more than one element. If the network is a loop with local exchange (LEC) and inter-exchange carrier (IXC) on two (2)

elements, failure of an element with LEC and IXC trunking would affect only the subscribers located on the element. The rest of the network would only suffer diminished performance.
Designing the Network
To design a network you must complete the following tasks:
Prepare an engineering plan
Determine the number and type of elements required
Determine the MSDN/DPNSS Network Resource Dimension required
Calculate the trunking requirements
Determine the method for interconnecting the elements
Establish the numbering plan.
Prepare an Engineering Plan
Before you begin, prepare an engineering plan for the site consisting of the following information:
Diagram of customer's existing systems or network
Diagram of customer requested or proposed network
Diagram of customer existing data communications
Diagram of customer requested or proposed data communications
Network node information sheet (one per node)
Number plan for existing node and network
Number plan for proposed node and network
Common carriers and resp ectiv e offering s
Local exchange carriers and respective offerings.
Determine the Number and Type of Elements Required
When determining the number of elements required, be sure to take future growth into consideration.
In configurations involving two to ten elements, PSTN trunking is designed with a target of 12% and MSDN trunking with the assumption that every element is connected directly to every other element with a minimum of one MSDN/DPNSS inter-element link. In actual applications, a realistic number of lines will be around 500 for a 3300 ICP system depending on configuration and applications.
Note: The maximum number of elements in a contiguous/campus cluster configuration cannot exceed ten. The following table illustrates absolute line/trunk maximums and peripheral/NSU node quantities. Every available port would be occupied unless otherwise indicated.

Calculate Trunking Requirements
Inter-element Trunking/Links
Inter-element trunking is MSDN/DPNSS, 23B+1D or 30B+2D. MSAN facilities can be used.
The following section is a worked example of how inter-node trunking requirements would be calculated. In practice the numbers to be used may differ, but the principles remain the same.
For elements installed in a campus or within a contiguous area, an inter-element link connects each element to every other element as a minimum. This minimizes tandem connections and involving more than two elements in a call.
This figure illustrates the connectivity between elements in a 10-element cluster installed in a campus/contiguous environment. Each element is connected to every other element by one link. In a campus/contiguous environment the number of elements will not normally exceed ten.
Additional links between specific elements will be provided when required to meet bid traffic requirements or conditions. These links are referred to as high traffic links. This figure shows a typical campus network with a high traffic link installed.
The first step in engineering the quantity of inter-element links is to determine the quantity required to support local traffic between the elements. It is most important that communities of interest/work groups/organization be confined to a single element to minimize inter-element traffic.
Use the following calculations to
Determine the total CCS/Erlang requirement per line per busy hour
Determine percentage trunk-in, trunk-out and local, per busy hour.
As an example, 900 seconds of traffic (9 CCS/.25 Erlang) per line will be used with 33.33% trunk-in, 33.33% trunk-out and 33.33% local. Local traffic represents 300 seconds, and for this calculation we assume 120 seconds is intra-element and 180 seconds inter-element. There will be 10 elements in the cluster so the 180-second inter-element traffic will be divided by 9. This allows for 20 seconds of traffic per line to each other element.

Assuming 1,000 lines per switch
1,000 lines X 20 seconds = 20,000 seconds 200 CCS/5.56 Erlangs
Using traffic tables at P.01 (one busy per 100 attempts) Grade of Service (GOS) requires 12 channels equal to 195 CCS/5.42 Erlangs. Therefore, 12 channels will be required between each element to support local inter-nodal traffic.
Inter-nodal connections are also required for trunk traffic when the element containing stations does not have LEC, IXC, or network trunking. Ideally, as a minimum, each element should have dedicated outgoing LEC trunks. Providing both incoming and outgoing trunks on each element further minimizes the need for inter-nodal connections. When possible, DID trunks should be obtained from the LEC in groups that provide the numbers as they relate to the element number plan. To do this, each element should, to the highest degree possible, have a unique number plan. Over a period of time, moving portable directory numbers across the cluster will affect the numbering plans at each element.
Specification
To calculate the inter-nodal links required to access or receive calls from external trunking, we will go back to the 900 seconds per line traffic requirement and make the following assumption:
40 seconds of the 300 seconds of out-trunking will be outgoing common carrier (IXC) traffic connecting to one element. (In this example, incoming PSTN trunk calls are considered to arrive at the local nodes).
This assumption implies that an additional 40 seconds of traffic per line must be accommodated between elements two through ten to element one. Therefore, for each element, we calculate:
1,000 lines X 40 seconds = 40,000 seconds 400 CCS/11.11 Erlangs
The total is now:
Internodal 200 CCS 5.56 Erlangs
-Outgoing IXC 400 CCS 11.11 Erlangs
--------------------------------------------------------------- ----------------------------­ Total 600 CCS 16.67 Erlangs
Using traffic tables at P.01 GOS, each element (elements 2 through 10) requires 22 channels, 600 CCS/16.67 Erlangs to connect to element one.

This example illustrates the advantage of using CEPT (30B+2D) for inter-element connectivity in campus/contiguous environments whenever possible. If DS-1 (23B+D) were used between elements 2-10 and element 1, two DS-1 circuits would be required. With CEPT (30B+2D) the 30 B-channels at P.01 provide 675 CCS/18.74 Erlangs with the requirements being local 200 CCS/5.56 Erlangs and trunk 400 CCS/11.11 Erlangs for a total of 600 CCS/16.67 Erlangs, so a single CEPT would suffice. At P.01 30 channels provide 732 CCS/20.34 Erlangs.

Trunking Between Elements
A cluster can be provided for a single campus/contiguous location or dispersed on a local, regional, national, or international basis. Many cluster applications will be combinations of one or more campus/contiguous locations and one or more dispersed remote elements.
Some applications will also require connectivity to other networks, or to systems that either are not part of the cluster or are not totally compatible with a cluster or MSDN/DPNSS.
This figure illustrates a regional cluster application, and this figure illustrates a nationally dispersed cluster connected to non-cluster applications.
Connectivity between contiguous and remote cluster elements always consists of MSDN/DPNSS links or MSAN/APNSS circuits. Connectivity between cluster elements and non-cluster systems and/or networks will consist of T1/D4 or analog E&M tie lines in North America, and it will adhere to national standards in CCITT areas.
The quantity of trunks between cluster elements and remote cluster elements, or cluster elements/remote cluster elements and non-cluster systems and/or networks, are engineered to meet actual traffic requirements or the customer specifications using Poisson or Erlang traffic tables. If acceptable to the customer, grades of service lower than P.01 may be used.
The engineer must be aware that this type of connectivity requires economic and/or business requirements to justify recommendations and implementation.
Public Switched Telephone Network Trunking
Public Switch Telephone Network (PSTN) trunking is provided by local exchange carriers (LEC) and common carriers, also known as inter-exchange carriers (IXC). Normally, a cluster element or group of cluster elements in a campus/contiguous application would be served by a single LEC. This is not always the case with common carriers. Multiple IXCs can connect to a single cluster element or group of cluster elements in a campus/contiguous application.
Connectivity from LEC’s and IXC’s can be digital or analog and an exact version will be determined by national standards. Examples are ISDN PRI, T1/D4, E1 with R-2 signaling, DASS, and various analog trunk signaling schemes.
T o minimize inter-element link requirements, each cluster element should, to the highest degree possible, have incoming and outgoing LEC service connected directly to it.
Special trunks, such as ACD, DISA, or dedicated, should connect directly to the cluster element where primary utilization will take place.
Common carrier circuits (IXC) should also connect to the cluster element where primary utilization takes place. Economic reasons may justify the bundling of IXC circuits and connecting to a cluster hub or main element where they would be utilized by more than one cluster element.
Survivability should also be considered in cluster-PSTN trunk engineering.

Determine the Method for Interconnecting Elements
MSDN/DPNSS Connectivity
Refer to the MSDN/DPNSS feature for information on network features.
Digital Signaling
MSDN/DPNSS provides call setup capabilities between systems connected in an MSDN/DPNSS network. MSDN/DPNSS uses a Common-Channel Signaling (CCS) scheme in which the signaling information for a number of traffic channels is passed as addressed messages over a single channel. The traffic information is carried on E&M trunks, and the digital signaling information may be carried on an analog or digital circuit.
Network Applications
MSDN/DPNSS can be utilized in all digital networks.
DS-1 Link
DS-1 offers a full duplex, point-to-point, 1.544 Mbps digital link with defined frame format. Each frame of a DS-1 link consists of 23 voice/data channels and one signaling channel, and it takes 125 microseconds to transmit. A DS-1 digital link cannot be set up between a DS-1 Formatter card and CEPT Formatter card.
The DS-1 digital link complies with the ATT DSX-1 standards. The technical characteristics of the DS-1 link are as follows:
twenty-four 64 Kbps traffic channels (23B + D)
one bit for terminal and signaling frame alignment
each channel has a sampling rate of 8,000 Hz at 8 bits per sample for a total of 64 Kbps. Each frame is then (24 x 8) + 1 = 193 bits. The total bit rate is therefore: 193 x 8000 =
1.544 Mbps.
Fractional T1
The common carriers offer fractional T1 services at a DS-0 rate of 56 Kbps. Using this service, and a voice/data MUX, provides an effective means of providing MSAN connectivity to a remote location (see MSAN Connectivity To A Remote Location).
Various manufacturers provide voice/data MUXs which can provide various combinations of voice and data (for example, 4 data and 4 voice over 56 Kbps DS-0 line).
XNET
XNET allows DPNSS trunks to be allocated to individual nodes on a switching basis. Rather than have dedicated links to each individual node, XNET allows a number of physical trunks to carry all traffic to all required nodes. The switching to appropriate end nodes is carried out at the PSTN or tandem exchange, and it is typically setup in a star configuration. The benefit

is the increased number of nodes that can be added to the network, and the reduced cost of interconnection tied lines.
CCITT (E1) to NA (T1) Connectivity
Connectivity can be provided between North American (23B+1D) and CCITT (30B+2D) with the common carrier providing proper channel matching. Twenty-three B-channel and one D-channel will be presented at the CCITT end. A DS-1 (E1/T1) Formatter card which inverts D-channel data must be installed in the North American element.

Factors to Consider
When engineering the numbering plan, you must consider the following factors:
Number of elements in campus/contiguous applications
Quantity of directory numbers required in campus/contiguous applications
Remote elements
Quantity of directory numbers required in remote elements
Telephone company exchange codes and DID number blocks
Ability of the telephone company to break down by trunk group DID numbers by thousands digit and hundreds digit

Ensuring Accurate Time Stamps
When multiple systems are used, multiple call records are produced. Within the call accounting mechanism, some type of sort criteria is used to "glue" together multiple call records, resulting in a complete model of the call. This model will include all the intermediate transitions in and out of tandem elements. Timing on these calls is very important to get an accurate report from the call accounting system.
Use the OPS Manager time synchronization feature to synchronize the time-of-day clock on all elements in a network to one second precision. This time synchronization feature also allows you to compensate for time zone differences where network elements are geographically dispersed.
Prevent Duplicate Trunk Numbers
Ensure trunk numbering across the network is sequential and unique. Flexible trunk numbering allows you to program trunks with trunk numbers from 1 to 9999.
Note: Do not confuse trunk numbering with the number of trunks.
Identifying Calls
The network node identification and the trunk number are included for incoming trunk calls that are routed across the network (see Network SMDR for details).
Voice Mail
Voice mail services in a network may be provided as follows:
On an individual node basis. Each node will have its own stand-alone voice mail system which will provide service to the users located on that node.
Each node could have its own voice mail system providing service to the users located on that particular node. These individual voice mail systems can be networked according to manufacturer's specifications to provide network services such as a broadcast list across the network.
A centralized system using a single voice mail system to serve either all network node subscribers or those users located on a group of network nodes. When such a system is provided at network nodes, the manufacturer's method of networking their systems can be used to further network these systems for multi-network applications.
Centralized Voice Mail Applications
Full voice mail functionality is obtained by use of the MSDN/DPNSS feature.

DPNSS callback message cancellation (voice mail usage only).
MSDN/DPNSS Voice V
MSDN/DPNSS Voice V provides

Typical Scenario in a Centralized Voice Mail Application
A trunk call is presented to extension 1234 and is forwarded to extension 5000 (COV voice mail) when no answer is received (see Centralized Voice Mail - Typical Scenario).
The COV voice mail display shows CFNA 1234, when the caller is forwarded to voice mail extension 5000. Voice mail answers the call and the caller leaves a message for extension
1234. The voice mail then goes off-hook, dials the voice mail activate feature access code (i.e., *20) followed by 1234. An ARS route has been established on Node A to route via an MSDN trunk (1 plus 3 digits = MSDN). The system dials 1234 and activates the message waiting lamp.
Note: Do not use *20 for ARS routes as this will cause a conflict with the network voice mail feature.
Message Waiting
Voice Mail Message Waiting indications are set from the main system by accessing the network trunks and outpulsing the Message Waiting activate/deactivate feature access code assigned on the remote system followed by the subscriber's extension number. The same feature access code is assigned on all systems unless the voice mail system can be assigned multiple message activate/deactivate codes; therefore, conflict dialing arises on the main site between the feature access code and ARS leading digits. The ARS leading digits for remote messaging will have to be programmed on the main system before the feature access code is assigned for Message Waiting activate/deactivate functions.

Page 53
Specification

Most voice mail systems require return dial tone after activating/deactivating message indications for confirmation. The conflict dialing timer for subscribers on the main site, may have to be adjusted through programming. Some voice processors are able to insert a "#" tone at the end of the dialed message wait string, which could be interpreted as "end of dial". Return dial tone would be returned immediately after the *#*, allowing quicker voice mail response and more digits to be dialed in setting another message indication without going on hook.
The message wait indications applied on the remote system will be considered "dial message waiting" messages not "callback messages".
Message Answering
Remote subscribers will reroute their calls to a defined ARS leading digit followed by their extension number. ARS will route the call through the network facilities to trunks on the main system where further digits will be outpulsed after accessing the centralized voice mail. The leading digit and extension number is passed through the network which will access the Loop Back or E&M Trunks on the main site. ARS digit modification for the trunks will outpulse the voice mail hunt group pilot number and insert a pause and any necessary tones followed by the extension number after the voice processor has answered. Calls rerouted will be offered the personal greeting of the subscriber.
Message Retrieval
Using "ONS Voice Mail" with "non-MSDN"; subscribers on the remote site may access the voice mail hunt group pilot number directly through ARS, although the user will be required to manually enter the appropriate DTMF tones to access their mailbox.
Alternatively, subscribers could retrieve voice mail messages by dialing a defined ARS leading digit followed by their extension number. This leading digit and extension number are passed through the network which will access the trunks on the main site. ARS digit modification for the trunks will insert the voice mail hunt group access code and outpulse the required codes and extension number to access their mailbox. Users will be prompted for their password.
Note: Advanced Analog Networking enhances message retrieval. ARS Modify Digits could insert the internal calling extension number automatically (i.e., <E>). Subscribers would simply dial a defined ARS digit string for message retrieval.
Using "COV Voice Mail with MSDN", remote subscribers call the voice mail hunt group pilot number directly through ARS. MSDN provides the subscriber’s extension number to the COV voice mail, allowing the voice processor to identify the caller as a subscriber. Voice mail then prompts the user for a password.
Messages can be retrieved external to the system dependent on incoming trunk access to the voice processor. Usually , subscribers will have to manually enter one or two digits followed by their mailbox number to log into their mailbox.

Trunks for Centralized Voice Mail
The node which provides the centralized voice mail using COV or ONS voice mail interfaces will require Loop Back Trunks regardless of network interfaces. When direct E&M analog connection to the voice mail can be utilized, Loop Back Trunks will not be required.
Call identity information that is required by voice mail systems for telephone answering is NOT presently part of the MSDN protocol. The trunks will be used to provide call identity to the voice processor; therefore, providing an efficient and easy to use voice mail interface for remote sites.
Loop Back Trunks
Any digital or analog E&M Tie Trunk may be used for Loop Back Trunks.
Traffic levels must be considered to determine the number of Loop Back Trunks required. Traffic will typically consist of rerouted calls for COV and ONS voice mail and message retrieval for ONS voice mail. E&M voice mail does not require use of Loop Back Trunks.
MSDN trunks will not ignore answer supervision. When the voice processor answers, an answer supervision signal is passed to the MSDN trunks and no more digits will be outpulsed to the voice processor. DTMF tones will not be received, resulting in improper call handling. Therefore, Loop Back Trunks are used on the Main system to ignore fake answer supervision allowing pauses and DTMF tones to be outpulsed to the voice processor for proper call handling.
In Voice Mail Connection with Loop Back Trunk, extension 5000 on the MAIN system is externally call forwarded to the central voice mail system on the remote system. The subscriber call reroutes to the ARS leading digit followed by his/her extension number "85000". The ARS programming in the MAIN system is programmed not to absorb the leading digit "8" allowing this digit to be outpulsed across the network to access the Loop Back Trunks.
The ARS for the Loop Back Trunks in the remote system is programmed to absorb the leading digit "8" and insert the voice mail hunt group pilot number "3000". The E&M Circuit Descriptor is programmed to insert the necessary pause in dialing before the remaining digits are sent. This will allow the voice mail system time to answer and receive the digits "5000", which route the caller to the associated mailbox.
Extension 5000 will retrieve voice mail messages by dialing the hunt group access code for "3000" on the remote system. No digits are absorbed or deleted on the main system.
Direct Connection to Voice Mail with E&M Trunks
If the voice mail system provided allows for direct E&M Trunk interface, this approach can be used eliminating the requirement for Loop Back Trunks. Analog E&M Trunks must be used to allow for flash transfer of calls.
In Voice Mail Connection with E&M Trunks, we have extension 5000 in system A externally call forwarded to the central voice mail system on system B. The subscriber call reroutes to the ARS leading digit followed by his/her extension number "85000". The ARS programming in system A is NOT to absorb the leading digit "8" allowing this digit to be outpulsed across the network to access the E&M Trunks to voice mail.

The ARS for the E&M Trunks in system B is programmed to absorb the leading digit "8". The E&M Circuit Descriptor is programmed to insert the necessary pause in dialing before the remaining digits are sent. This will allow the voice mail system time to answer and receive the digits "5000", which route the caller to the associated mailbox.
Extension 5000 will retrieve voice mail messages by dialing the ARS digit string defined for message retrieval followed by their extension number "8*5000". The ARS - modify digits in system A will not absorb or insert any digits so the E&M voice mail ports can be accessed on system B. ARS on system B will absorb the leading digit "8". The E&M Circuit Descriptor is programmed to insert the necessary pause in dialing before the remaining digits are sent. This pause allows the voice mail time to answer and receive the digits "*5000", which routes the subscriber’s call to the subscriber’s mailbox. The subscriber on extension 6000 on system B retrieves messages in the same manner by dialing "8*6000".

Third Party Network Devices
The following devices may be used in digital networks with MSDN and non-MSDN applications to support customer data requirements:
Drop and Insert
Channel Signaling Unit (CSU)
Channel Bank
Multiplexer
Inverse Multiplexers. Note: This section contains general guidelines for designing configurations that use these
devices. See the manufacturers' specifications for specific instructions.
Drop and Insert (D/I)
Drop and Insert (D/I) provides an economical means to directly access a T1 (1.544 Mbps) transmission system or a CEPT (2.048 Mbps) transmission system. This includes DS-1 or CEPT circuits connecting MSDN network nodes and direct T1 or CEPT connections. Mitel systems connected to other vendor systems with direct digital (T1 or CEPT) connections are also accommodated.
The D/I devices connects to the DS-1 or CEPT line drops/inserts information into the desired time slots and passes the remainder of the channels through on a digital basis.
Voice, data, television, and audio program channels can be dropped/inserted. The data channels can be configured to provide 56/64 x N synchronous data in some versions. The number of channels that can be dropped/inserted depends on the method used, and the manufacturer and the manufacture's model type. In theory, with some devices, 24 channels
Release 3.2 4
Page 56

300 ICP Hardware User Guide
4
can be dropped/inserted. Note that MSDN DS-1 links are limited to 23 channels because channel 24 is used for signaling.
The only advantage of switched data arrangements over drop/insert is when alternate routing is provided. Switched circuits can be configured to reroute automatically in case of primary route failure.
The following D/I devices are supported:
Channel Service Unit (CSU)
Channel Bank
Multiplexer.
Channel Service Unit Drop/Insert
Drop/Insert Channel Service Units (CSUs) are available from various manufacturers and replace the standard CSUs used to connect the T1 span line to the system. Versions provide for 2 or 4 drop insert connections which are V.35 or RS-232 compatible. Speeds of up to 64 Kbps are supported. Some manufacturers have a 19.2 Kbps version.
Channel Banks for Drop/Insert
Channel Banks can also be used for drop/insert applications because two are required at each end. This can be a costly, not very efficient arrangement. The circuits dropped/inserted can be voice, data, or audio programming with the only limitation being the term sets available.
Drop and Insert Multiplexers
Drop and Insert Multiplexers (D/I MUX) provide an economical means to directly access a standard T1 (1.544 Mbps) digital transmission system. The D/I MUX provides dropping/inserting voice, data, audio program or TV channels. The D/I MUX is more cost-effective and provides better transmission quality than back-to-back channel banks. The D/I MUX can be configured to drop or insert "N" amount of channels (See manufacturer's instructions). Note that MSDN DS-1 links are limited to 23 channels because channel 24 is used for signaling.
The D/I MUX connects to the DS-1 line, drops/inserts information contained into the desired time slots, and passes the remainder of the channels through on a digital basis. The D/I MUX should pass bipolar violations unchanged to accommodate span line testing and 64 Kbps clear channel operation. In the event of an internal failure, the D/I MUX should automatically bypass the line.
The D/I MUX, normally, can be configured for communication up or down the span line, or both. Typically, communication will be toward a network system node where switching equipment and access to other networks is located. The D/I MUX can operate in systems terminated by digital switches or conventional D3 and D4 channel banks. It should be compatible with D1D, D2, D3, and D4 mode 3 frame formats.
The D/I MUX should be designed to be used at customer premises and along cable, digital microwave, and fiber optic span lines. For voice and data channel access, the manufacturers

have a number of different modules which vary depending on circuit type, signaling data rates, etc. Single channel synchronous data rates that are multiples of 56 or 64 Kbps, up to 1.536 Mbps, should be accommodated.
The D/I MUX can be used to drop and insert information for transmission in one direction (unidirectional) or two directions (bidirectional). The number of channels dropped and inserted may be up to 24 depending on the manufacturer’s configuration. The primary function performed by the D/I MUX is to provide access to a T1 line which is a full-duplex transmission medium.
In general, a typical system operates as follows: a T1 line enters the D/I MUX and drops off selected DS-0 channels which are received by the channel units, the channel unit then interfaces the baseband signals with the subscriber. In the reverse direction, the channel unit converts subscriber transmit information into a signal compatible with the D4 channelized T1 format which is then inserted into the T1 bit stream. All DS-0 channels not accessed pass through the D/I MUX.
Inverse Multiplexing
When given a single telephone number, an inverse multiplexer dials multiple digital "calls" between two sites and combines the bandwidth of the individual calls into a single, high-bandwidth channel. The inverse multiplexers at each end perform dialing, delay compensation and reordering tasks, and monitor and maintain the integrity of the connection. Inverse multiplexers can also combine leased and dialed bandwidth.
Inverse multiplexers can provide suitable bandwidth for data and video applications at rates from 56 Kbps to 4 Mbits using dialed and leased services depending on the manufacturer. Inverse multiplexers provide dynamic allocation of frequency and ISDN H-0, H-11 type services.
ISDN Basic Rate (BRI) an d Primary R ate (PRI) li nes provide access to swi tched and de dicated services within the wide area network (WAN), including 56K for T1 lines and 64K for E1 lines.The BRI card provides either 56K or 64K bandwidth per channel but does not perform any channel aggregation. An inverse multiplexer or similar device would be required to combine multiple switched 56K or 64K service channels for higher bandwidth.
Typical features on inverse multiplexers are:
Field-selectable V.35, RS-449, or X.21 data ports
RS-366, V.25 bis, X.21, and control-lead dialing
Dual 56 ports for 112 Kbit/s operation
Exact clocking and 56-64 Kbit/s rate adaption
Speed dialing and stored call profiles
Supports conference scheduling software
Supports video
Nx56, Nx64, and Nx384

MSDN Applications
Inverse multiplexers will be connected to system network nodes with T1/D4 circuits. When not in use, no circuits will be connected and no MSDN B-Channels will be occupied (see example).
In the example, the inverse multiplexer located in Dallas has dialed digits to set up DS-0 connections in both the Dallas and Kanata nodes. Six bearer (B) Channels on the first MSDN circuit were utilized. A bandwidth of 336/384 Kbps (H-0) is provided. Call set-up is flexible. DS-0 circuits within the system do not have to be sequential or in the same MSDN circuit. The six DS-0 connections required are distributed through both of the connecting MSDN circuits.
With a single MSDN circuit call, call set-up would be restricted to twenty-three DS-0 circuits (B Channels). Channel 24 is reserved for D Channel. When multiple MSDN circuits are available, rates above 23 X 64 Kbps can be set with the appropriate number of DS-0 (B Channels) distributed over the multiple MSDN circuits. Bandwidth Exceeding 23 x 64 Kbps Multiple MSDN Circuits illustrates a 1536/1344 Kbps (H-11) arrangement with twenty-four DS-0 circuits distributed over two MSDN circuits.
LAN/WAN
LAN Guidelines
T o maintain optimum voice quality, it is recommended that voice and data traffic be segregated as much as possible. There are three methods of segregation, depending on the existing LAN configuration:
1. Run Voice and Data on separate physical networks
2. Run Voice and Data on separate Virtual LANs (VLAN).
3. Use a separate subnet for voice traffic.
LAN Recommendations:
Use Ethernet switches instead of hubs. It is recommended that IP telephones be in a single sub-net incorporating Layer 2 switches.
Use Full Duplex Fast Ethernet where possible between switches.
For the single-port telephones (4015 IP Phone/4025 IP Phone), provide two switched Ethernet drops to the desktop -- one for the PC and one for the IP telephone.
For the dual-port telephones (5010 IP Phone/5020 IP Phone), you have two options. First, provide one switched Ethernet drop to the desktop for the PC/IP Phone. In this case, the PC connects to the network through the IP telephone. Second, provide two switched Ethernet drops, one for the PC and one for the IP telephone. For optimum voice quality, VLANs are highly recommended where only one Ethernet drop to the desktop is used.
The 3300 ICP system should be installed in the same broadcast domain as the majority of the IP telephones.
There should be only one active Dynamic Host Configuration Protocol (DHCP) server within the Broadcast Domain. The 3300 ICP system includes a DHCP server.
0 Release 3.2
Page 59
Specification
s

Place functional groups on the same switches and/or subnets to reduce traffic across backbones and routers.
IEEE 802.1 p/Q priority is supported at the telephones but not supported on the Mitel Networks 3300 Controller. Use Layer 2 Switches (port based) to set the voice VLAN default for the 3300 Controller, and to modify the data format to add 802.1 p/Q (tagging).
When VLANs (802.1 p/Q) are used with the dual-port telephones (5010 IP Phone/5020 IP Phone), the Layer 2 switch ports connected to IP telephones must have the port con­figured to accept data already tagged for the voice VLAN and a default or native VLAN (typically set to 1) to accept untagged data from an attached PC and convert it to tagged data.
Do not mix data and voice with the same priority. Set any queues and priority so that voice and data are different priority (for example, High - Voice, Low - Data).
For mobility of IP telephones, it is recommended that Layer 2 switch ports configured for operation with the 3300 ICP server and IP telephones should have "spanning tree protocol" disabled and/or configured to "Portfast". It is important to ensure that the telephones and 3300 Controller are not connected to the network such that they could introduce a network loop.
This system supports G711 voice encoding between IP telephones.
WAN Guidelines
Recommendations for connection across a Layer 3 switch or router:
To forward a DHCP request across a Layer 3 switch or router, activate DHCP forwarding (DHCP Helper) on the router. Alternatively, use a secondary DHCP server on the remote side of the Layer 3 device. This secondary DHCP server must programmed with the same options as the main DHCP server for the telephones to operate properly.
For optimum performance and voice quality when using IP telephones across routed links the routers should be configured to prioritize voice traffic based on Type Of Service (TOS) using techniques such as Weighted Fair Queuing (WFQ). IP phones are preset to prece­dence 5 with Minimum Delay. A high priority queue has settings 4, 5, 6, 7; A low priority queue has settings 0, 1, 2, 3. PCs should use low priority. On slow WAN links between routers set the Maximum Transmittable Unit (MTU) appropriately for the speed of the WAN link (a value of 500 is recommended for links using T1/E1 type seeds).
Not all routers or Layer 3 switches will recognize 802.1p/Q VLAN information. In this situation, it will be necessary to provide a separate physical connection for each VLAN and subnet in use.
The E2T / RTC Cards support the Internet Control Message Protocol (ICMP) Messages. Enable ICMP Redirect on your layer 3 switches and default gateway. The redirect will forward messages to the correct LAN segment and reduce broadcast messages and LAN usage.
Minimum recommended WAN link speed is 1.544 Mbps (T1) with Frame Relay, HDLC, PPP, and compressed PPP.
If the Layer 3 switch or router can support TOS and queue priority, then don't use more than 70% bandwidth. If the Layer 3 switch or router cannot support TOS queue, then no
Release 3.2 5
Page 60
3
300 ICP Hardware User Guide
5
more than 40% bandwidth should be used. The usage of the link should be determined before installing IP phones to determine the level of operation possible. A heavily used link may require an upgrade or implementation of TOS and MTU (500) settings.
Plan the Network
The 3300 ICP system is available in four main configurations:
1. IP tel eph one onl y
2. Analog Services Unit only
3. IP tel eph one and Analo g Ser vic es Uni t
4. ICP system with Peripheral and/or DSU Units.
When the 3300 ICP system is installed with the IP telephone option you will need two IP addresses for the system ( E2T, RTC) and a range of IP addresses for the IP telephones.
The 3300 Controller uses a number of fixed IP addresses internally. It is highly recommended that IP addresses in the following range, NOT be present within the network: 192.168.10.X to
192.168.13.X. The 3300 Controller includes an internal Layer 2 switch for local communication. Only one connection is required to connect the unit to the network; this port should be set to Auto Configure, and should be connected to operate with 100BaseT for optimum performance. The remaining connections can be used for voice application devices, or left as spares. They should not be used to carry network traffic, other than that destined for the 3300 Controller. This will minimise unwanted data traffic which would otherwise reduce available connection bandwidth.
Note: The Real Time Complex (RTC) is used for the IP telephones signaling and also DHCP, TFTP, etc. Call progress, device status and screen updated messages are sent between the IP telephones and the RTC. The E2T (Ethernet to TDM) card is where the Ethernet voice is converted to TDM and vice versa.

E2T Compression
The 3300 ICP provides the option of G.729a voice compression. Licenses and the 21161 Quad DSP Modules enable this feature to a maximum 64 compression channels. Compression is carried out by the 21161 DSP under the control of the E2T.
IP phone to IP phone calls also support compression. Compression for this scenario is applied by DSP resources in the phones and does not require compression licenses.
The compression of a standard call effectively reduces the bandwidth required per call from 64kbps to approximately 8kbps plus packet overhead.
Note: Only IP phones can be put in separate compression zones. The TDM resource of the system is always left in the default zone.
In the following example, when an IP device (assigned to a non-default zone) calls a TDM device, G.729ac compression will be invoked on the LAN or WAN side of the call providing there are adequate compression resources available in the controller. The same applies to calls originate from a TDM device and terminate on an IP device.

3300 R2 NSU Protocols
R2 is a protocol converter that allows the 3300 R2 NSU to access an R2 National Public Switched T elephone Network (PSTN) using MF-R2 digital trunk signaling. The 3300 Controller also receives and processes Calling Line Identification (CLI) and allows the information to be displayed on the user's telephone display screen.
The 3300 R2 NSU supports the CCITT Blue Book, Volume VI, Fascicle VI.4, Specifications of Signaling System R2, Recommendations Q.440 to Q.490 (with the exception of Echo Suppression (Q.479), Test Calls (Q.490) and international signals).
The 3300 R2 NSU converts the following:
Incoming MF-R2 signals from the PSTN into Digital Private Network Signaling System (DPNSS) signals for the system
Outgoing DPNSS signals from the system into MF-R2 signals for the PSTN.

The German variant has LS function only. The trunk circuits on the LS/GS trunk card are configured during the initial system programming
process. Each trunk circuit can be programmed to operate in an LS or GS mode. LS or GS options can be changed at any time via the System Administration Tool.
When GS mode is selected, incoming trunk calls are initiated by a ground on the Tip lead, or by a ringing source applied to the trunk by the CO. Outgoing calls are initiated by seizing an idle trunk (via the DATA IN link of the trunk circuit) and by placing a ground on the Ring lead.
When LS mode is selected, incoming trunk calls are initiated by a ringing source applied to the trunk by the CO. Outgoing calls are initiated by first seizing an idle trunk (via the DATA IN link on an LS/GS trunk card circuit) and by placing a low resistance loop across the Tip and Ring leads.
Dictation equipment used on a trunk can indicate a busy or idle status by interconnecting a third wire lead to either the T(MR) or R(MR) termination at the 3300 ICP system. The actual configuration that should be used is dependent upon the type of centralized dictation equipment used and its busy status (i.e., whether a busy condition is indicated by a voltage or ground condition on the third wire; see Dictation Access in Troubleshooting, Hardware, Peripheral Unit, LS/GS Trunk Card).
In addition, T(MR) and R(MR) leads can be connected to the CO for message registration purposes. The system can record message registration pulses either by polarity reversal over the Tip and Ring leads (when the called party answers) or by loop signaling from the CO over the second pair of leads. Various types of terminations can be used for message registration pulses transmitted from the CO. In each case, M and MM leads terminate respectively on the T(MR) and R(MR) leads. A message registration signal is given when the MR contact at the CO is closed.

Guidelines for Handling Fiber Optic Cable
Never touch the tip of a fiber connector. Cleanliness of the connector ferrule (tip) is impor­tant for error free transmission.
Always place the dust caps onto the connectors immediately after disconnecting.
You can clean the ferrule tips on the connectors with ethyl-alcohol.

Fiber optic cables are often more easily installed and pulled than copper because of their light weight and flexibility. However , take care not to exceed the minimum bend radius or maximum tensile strength.
Procedures for the repairing, splicing, or assembling fiber optic cables are available from fiber component manufacturers (many offer training courses).
WARNING: Fiber optic sources emit infrared light that is invisible to the human eye. Never look directly into a source or into the end of a fiber energized by a source because it can damage the retina. When working with raw fiber optic cable, be careful of the fiber ends or slivers that can puncture the skin or cause irritation.
Specifications
At each end of a fiber optic cable is a Fiber Interface Module (FIM). At the transmitting end, the FIM converts electrical signals into pulses of light to be transmitted over the cable. At the receiving end, the FIM converts the pulses of light back into electrical signals usable by the node.
The FIM connects the 3300 Controller to a peripheral unit or DSU. These FIMs cannot be installed in the Applications Gateway. Each FIM variant may be identified by its optical wavelength and fiber type (indicated on the FIM faceplate). The same FIM variant must be used at each end of a fiber optic cable. However, a node may be equipped with different FIM variants to suit the length of each cable run.

Operation
The FIM has three functional sections: a transmitter, a receiver, and a control section.
The transmitter section accepts data from the node in which it is installed. The data is converted to byte-interleaved format, and a checksum is calculated. The checksum byte is combined with the data and the frame synchronization information. The frame is encoded as serial data and transmitted on the fiber.
The receiver section converts the incoming data to parallel format, extracts the frame synchronization information, and decodes the data. Control and status information are extracted and further decoded. The checksum is verified and an error counter updated. The status information and data are combined, frame-aligned, and re-formatted for output.
The control section generates control signals and the transmit clocks. This section also regenerates the telephony clocks for the peripheral nodes, and provides status information for the Main Controller.
Two LEDs indicate the detection of local and remote clocks.
DID/Loop Tie Trunk Card
The DID/LT T runk card terminates up to four trunks. These trunks can be Direct Inward Dialing (DID) trunks, Loop Tie (LT) trunks, or any combination of DID and LT Trunks. Direct Inward Dialing provides direct access to system subscriber lines from the public telephone network. Loop Tie provides a means of connecting two systems together over a common trunk.
The assignment of trunk types is programmed through the System Administration Tool. Programmable parameters include Dial-In Trunk versus Non-Dial-In Trunk and Loop Pulsing versus Battery Ground Pulsing.

connected. Outgoing calls are converted from PCM digital signals to analog signals by one of the 16 line circuit modules on the ONS line card. Calls are switched by the Main Controller and the two parties connected.
All signals are passed through the 2-wire to 4-wire hybrid circuit on the line circuit module. The line busy status LED remains lit while the call is in progress. When calls are terminated, receipt of an on-hook condition turns off the line status LED. The call is disconnected from the circuit switch and the line circuit reverts to an idle condition.
The ONS line card provides for “Ground button” signaling. A ground button, on a telephone extension so equipped, provides a means of connecting ground to the ring lead. In addition to ground button support, the ONS line card features a calibrated flash function. Unlike telephone installations using ground button signaling, telephone extensions using calibrated flash signaling do not require a third wire connected to ground. Calibrated flash is also the only method recognized internationally for recall simulation. The minimum calibrated flash duration that can be detected by the ONS line card is 40 milliseconds.
ONS CLASS/CLIP Line Card
The ONS CLASS/CLIP line card supports the same functionality as the ONS line card, but also provides CLASS/CLIP functionality when enabled by the software. The ONS CLASS line card is available in North America, and the ONS CLIP line card is available in the UK. The ONS CLASS/CLIP line card installs in any Peripheral Interface card slot, and is hot-swappable.
Note: Sending CLASS/CLIP information to an ONS line card will not harm the card.
ONS CLASS Line Card Specifications (North America)
The ONS CLASS line card (NA) supports ONS CLASS sets (NA) that meet the following specifications:
- ANSI/TIA/EIA-716 Standard "T elecommunications T elephone T erminal Equipment - Type 1 Caller Identity Equipment Performance Requirements"
- ANSI/TIA/EIA-777 Standard "T elecommunications T elephone T erminal Equipment - Type 2 Caller Identity Equipment Performance Requirements".
For more information on ONS CLASS/CLIP line card specifications, see ONS Line Card.
OPS Line Card
The OPS line card connects to any Peripheral Interface card slot. The OPS line card is a digital card intended to be used to interface up to eight outside telephone extensions with the system. The card is meant to interface telephone extensions whose line loop resistance exceeds 400 ohms. As such, the OPS line card is used to connect external telephone systems whose loop resistance is anywhere from 400 to 1600 ohms (external resistance from 600 to 1800 ohms).
