Office Communicator

DEFINITY and the Avaya R300

The Avaya R300 provides an integral solution to support the complete communication
needs of a small office (24 clients or less) for LAN data clients and digital/analog voice
terminals. The A vaya R300 supports IP routing through its integrated WAN interfaces (T1,
E1, BRI, and serial) to the R9 or newer DEFINITY.

November 2000

Issue 1

1DEFINITY and the Avaya R300

From a control perspective, all call processing, call routing, and billing are managed in the
DEFINITY control cabinet. The Avaya R300 operates similarly to a DEFINITY EPN. The
Avaya R300 Remote Office Communicator provides local access trunks (digital and
analog), and the DEFINITY manages these as IP signaling groups.

This remote application, based on Lucent-Ascend’s MAX 3000, provides you with an
effective way to maintain remote DCP and analog phones and trunks from a DEFINITY
Enterprise Communication Server (ECS). The Avaya R300 provides full DEFINITY
functionality and features to the remote site either through a WAN or LAN using the IP
protocol.

Since the Avaya R300 Remote Office Communicator is based on Lucent-Ascend’s MAX
3000, you may see references to Lucent-Ascend’s MAX documentation. That
documentation can be found on the DEFINITY documentation CD shipped with the
Avaya R300.

DEFINITY Remote Office overview

DEFINITY Network

The “main” DEFINITY cabinet may be a G3R, a G3SI, G3CSI, DEFINITY One, or an
Avaya IP-600. The DEFINITY cabinet may either be a PPN (Processor Port Network) or
an EPN (Expansion Port Network). The DEFINITY software must contain a Release 9 or
newer release software.

Two DEFINITY hardware boards are used to support the Remote Office; the C-LAN
(TN799C) and the IP Media Processor (TN2302AP). The C-LAN board is used to convey
signaling/control streams over to remote station endpoints and to remote trunks (that are
supported on the Avaya R300). The IP Media Processor card serves as the voice bearer
gateway and audio conference bridge for transporting TDM-based traffic from the
DEFINITY backplane (supporting traditional line and trunk cards) out to the IP-based
wide area network and on toward the Remote Office.The C-LAN and the IP Media
Processor mu st be in the same network regi on (as DEFINI TY defines an IP networki ng
region). Figure 1 below shows the network topology for a DEFINITY ECS main system
with two subtending remote office configurations.

November 2000

2DEFINITY Remote Office overview

Figure 1. DEFINITY Remote Office Network Topology

The “network” connection to the C-LAN card is a 10 BaseT and 100 BaseT Ethernet
connection. The “network” connection to the IP Media Processor is a 10/100 BaseT
Ethernet connection. This Ethernet output of these two cards is connected to the host LAN
which is a subnetwork consisting of data switches and/or hubs and interior routers.

From the host LAN network, the control and bearer IP traf fic streams are directed via Host
WAN Access equipment to the WAN. This WAN access equipment typically would
consist of the following components:

■ Router to serve as the IP gateway from the enterprise premises out to the IP-based

WAN.

■ Access Concentrator to multiplex the LAN and TDM-based enterprise traffic

streams into an aggregated stream to present to the wide area network.

■ Optionally a VPN service for providing enha nced secu rity, particularly for data

services.

■ Optionally a Frame Relay Access Device (FRAD) to wrap the traffic into a frame

format suitable for transport over an enterprise network based upon frame relay
PVC service.

This WAN access equipment may be provided by one or more physically separate
products, and these products may be provided by different vendors. The industry trend is
for increased consolidation of this equipment.

The central wide area network services (shown as a cloud in the center of Figure 1 on page

2) can be an enterprise network, a PSTN switched network or a combination of the two.

The technologies of the WAN may be a variety of services including frame relay, ATM,
ISDN or digital T- carrier. In all cases, this DEFINITY Remote Office application will
provide both the signaling and voice bearer traffic in IP -based protocol frames that are
transported over the underlying physical frame formats.

Avaya R300 network

At the far side of the W AN is the A vaya R300. You can have multiple Avaya R300 devices
that subtend via the WAN back to a main DEFINITY system.

The Avaya R300 provides the following features:

■ Support for up to 24 DCP digital two-wire sets: 6400-series, 8400-series, or

9031DCP Transtalk model (wireless base st ation).

■ Support for two analog stations to which analog phones (6200-series or

2500-series) or analog fax machines may be connected.

■ Support for local switch ing between the analog and DCP station sets out through

local central office trunks. These local trunks (local to the remote site) may be
either digital through T1/E1/BRI WAN access trunks or, in North America,
through 600 ohm analog trunks.

In addition to voice telephony features, the Avaya R300 provides the remote site the
opportunity to integrate data and provides a conversion of voice and data applications in
the same product.

DEFINITY Enterprise Communication Server Release 9

Specifically, the Avaya R300 provides:

■ WAN access via E1, T1, BRI (BRI-S/T 4-wire or BRI-U 2-wire), and serial WAN.

■ Ethernet 10/100BaseT interface to provide IP routed connectivity to the local LAN

in the Remote Office. (This interface is a dual routed port.)

■ An IP router that is capable of supporting both interior and exterior gateway

routing protocols (RIP V2 and OSPF).

■ A V oice Over IP (VOIP) gateway to convert TDM-based audio streams (from DCP

and analog phone sets or inco ming digital and analog trunks ) into IP-based st reams
for transport to/from the main DEFINITY site, or other IP-connected DEFINITY
remote sites and/or IP phones and IP softphones.

■ Support for CODECs including G.711 (A-law and U-law), G.729, and G.723

This digital WAN interface is based on four product models:

■ MX30-2T1-AC which contains two T1 interfaces (available in North American

and Japanese models).

■ MX30-2E1-AC which contains two E1 interfaces.

November 2000

■ MX30-6ST-AC which contains six BRI 4-wire S/T interfaces.

■ MX30-6BU-AC which contains six BRI 2-wire U interfaces.

NOTE:

The T1/E1 WAN interfaces are capable of supporting robbed bit service, ISDN
Primary Rate service (both in full T1/E1 and FT1/FE1 modes), and frame relay
service. The North American T1 interface is capable of supporting up to
twenty-three 64 Kbps channels for PRI and twenty-four channels for robbed bit
signalling. The International E1 interface is capable of supporting up to thirty, 64
Kbps bearer channels.

NOTE:

The ISDN Basic Rate interface is capable of supporting two 64 Kbps channels.

DEFINITY call processing for the Avaya R300 stations & trunks

The trunk facilities within the Avaya R300 are under the management of the main
DEFINITY switch. The Avaya R300 operates as a:

■ Line-side gateway to represent the 24 digital and 2 analog stations to DEFINITY

as IP phones.

■ Trunk-side gateway to represent the PSTN wide area network digital and analog

services to DEFINITY as IP trunks.

The Avaya R300 operates as a “line side” gateway to translate the TDM-based digital and
analog telephone stations and present them to DEFINITY as if they were “native” H.323
IP phones. It should be noted that the DEFINITY maintenance and administration of the
lamp displays and button control are maintained exactly in accordance with existing
DEFINITY CCMS messages. These “custom” DEFINITY messages are tunneled over the
TCP/IP connections to the Avaya R300.

The Avaya R300 operates as an IP trunk gateway for the management of digital trunks
(T1/E1, BRI) and the analog trunks. Each element of the PSTN trunks can be mapped to
be represented to DEFINITY as an IP Signalling group member. This allows all of the
DEFINITY application features such as ARS and Multi-Location Routing to be employed.

5DEFINITY ca ll processing for the Avaya R300 stations & trunks

In effect, the Avaya R300 operates as a “virtual” EPN to DEFINITY. Figure 2 shows how
DEFINITY call processing views the resources within the Remote Office.

DEFINITY to remote office signal flow

Signaling messages (as part of call processing) are sent from the Switch Processor
Element (SPE), across the internal DEFINITY backplane bus, and forwarded to the
C-LAN module. From the Ethernet output of the C-LAN board, the signaling information
is wrapped in IP packets and sent across the WAN over to the Avaya R300. The Router
Engine in the Avaya R300 directs these wrapped signalling packets across the API to the
Remote Angel (on the Combo Blade).

For a main site supported, digital station set, the bearer information is communicated from
the digital line card (for example, DCP) onto the DEFINITY TDM backplane bus and sent
over to the IP Media Processor. The Media Processor performs the TDM to IP gateway
conversion per the H.323V2 protocol.

The IP based bearer stream is communicated across the WAN to the Avaya R300. The
A vaya R300 receives the IP stream and rou tes it to its internal VOIP gateway, where the IP
Voice stream is converted back to TDM and passed to the Cmombo Blade. Then the
Combo Blade transforms this into an I-channel of the DCP communication channel and
sends it to the DCP digital station.

The Avaya R300 can be connected to a WAN using two principle topologies:

■ Direct connection from its WAN ports (T1/E1, BRI, analog trunk) to the WAN

service provider

■ Connection through your existing equipment that serves as the principle WAN

service access point.

The illustration in Figure 3 on page 6 depicts the topology which could be more
commonly u s ed in deploy ments of newly configu re d Remote Offic es. This topology has
the Av aya R300 serving as the principle point of WAN access via its WAN ports. The
A vaya R300 offers the ability to offer both T1/E1 ports, along with two analog trunk ports.
The configuration of available port types will depend on the model of the Avaya R300 unit
(2-T1 or 2-E1 or 6 BRI). The configuration of network resources (what you actually
subscribe to from your WAN service provider) determines what ports on the Avaya R300
are actually used. T1/E1 trunks may be c onfigured in a fraction al mode. The Avaya R300’s
Ethernet port can connect to subtending router(s) if your local LAN configuration is this
size.

7Avaya R300 with existing WAN access equipment

When the Avaya R300 co-exists (subtends) in an office environment with existing WAN
access concentration/routing equipment, two configurations are available:

■ Connection via its Ethernet port over to the local IP LAN (see Figure 4 on page 8)

■ Connection via its Serial WAN port (V .35) over to the Serial inpu t of a WAN router

(see Figure 5 on page 8)

The Avaya R300 offers the ability for DEFINITY call routing to use local access trunks.
These local access trunks may be directly connected to a WAN service provider network,
or the T1/E1 WAN trunks may be subtending to an existing drop and insert T1/E1
connection on the existing WAN access equipment.

The Avaya R300 offers the ability to offer both T1/E1 ports, along with two analog trunk
ports and BRI ports. The configuration of available port types will depend on the whether
the Av aya R300 is a North American or global unit. The configuration of network
resources (what you actually subscribed to from your WAN service provider) determines
what ports on the Avaya R300 are actually used. T1/E1 trunks may be configured in a
fractional mode.

Avaya R300 with local LAN supported IP Softphones and telephones

The Ethernet interface of the Avaya R300 can connect to your LAN with both native
IP-based data clients, as well as native IP-based voice clients. In Release 9, both IP
Softphones (IP voice client application) resident on your PC; or the new Model 46xx IP
telephones will be available.

The IP-based voice and data clients will be connected in a subnet. This subn et is provid ed
by point-to-point serial Ethernet connections to a Level 2 Ethernet switch. The uplink of
this subnet is connected to the Ethernet port on the Avaya R300. It is important that
voice-over-IP clients be connected to switched Ethernet hubs rather than to shared
Ethernet hubs. (See Figure 6 below.)

Emergency transfer at the DEFINITY Remote Office

The Av aya R300 Emergency Transfer feature provides some limited telephone service in
the case of disaster. This feature enables a relay contact set to directly cut-through the tip
and ring of the two analog station ports and to connect them to the two wire analog trunk
interface. These two analog stations operate in a loop-start trunk mode (for example, go
off-hook to seize an out-going CO trunk connection). See Figure 7 on page 11.

NOTE:

The DCP stations do not operate in this failure mode.

The Emergency Transfer relays operate by:

■ Loss of power on the Avaya R300’s Combo Blade

■ Failure of the Keep-Alive regis tr a tion m e ssage, indicating loss of connectivity

back to a main DEFINITY site.

System management for the Remote Office

Avaya R300 Administration

The system management of the Remote Office consists of two functional subsystems:

■ DEFINITY main switch

■ Avaya R300 voice/data switch

The DEFINITY is managed for administration via a SAT interface and/or via the
DEFINITY System Administration (DSA) or DEFINITY Network Administration (DNA)
tools. The Lucent-Ascend Command Line Interface manages the administration of the
A vaya R 300. Within the Avaya R300, the TAOS operating system is designed to support a
menu-driven administration system. This system provides for the full administration of the
Avaya R300 Combo Blade’s voice features. Figure 7 on page 11 shows the current tools
available for configuration management on the Avaya R300.

Avaya R300 Fault Management

The NAVIS Access network management tool or a SNMP manager manages the Avaya
R300 for fault and performance. As long as your network connection supports IP-based
communication, the NAVIS system can communicate with the Avaya R300. The NAVIS
Connect system (PC-based) may communicate with the Avaya R300 via a WAN-b ased IP
network, a local LAN, or with a directly connected serial communications port.

The DEFINITY is managed for fault and performance via a SAT interface and/or via the
DEFINITY Network Management (DNM) system. The DEFINITY Network
Management (DNM) product as well as the Lucent-Ascend’s NAVIS Network
Management product operate on the HP OpenView network management application
platform. In fact, they both can concurrently run together under a common platform. See

Figure 8 on page 12.

NAVIS Access is supported on the following platforms:
* Windows NT 4.0
* Solaris 2.5 (Sparc, Intel)
* SunOS 4.1.4
* HPUX 9, HPUX10
* AIX 4.1
* BSD/OS 3.0

What is the Avaya R300?

The Av aya R300 is a small, rack-mountable unit (1.75 in. x 17.5 in. x 17 in.) that features
two expansion slots. The right slot, as you look at the front of the unit, houses a DSP blade
(for Voice over IP option). As you look at the back of the unit, an other slot h ouses the new
Combo Blade. The Combo Blade supports 24 two-wire Digital DCP stations, 2 analog
stations, and 2 analog (600 ohm ) loop start trunks . A single DEFINITY sw itch can support
multiple Avaya R300 units as described in Table 1.

The Av aya R300 and DEFINITY IP Solutions endpoints use common DEFINITY call
processing resources, therefore the number of Avaya R300 units that can be supported is
additive, not mutually exclusive with the number of IP Solutions endpoints supported.

The Avaya R300 provides a cost-effective method for providing the full range of
DEFINITY functionality at a remote site. The remoted telephony has all of the capabilities

of that which is “directly connected” to the DEFINITY switch at the main site. The A vaya
R300 also provides voice and data convergence as voice and data can share the same
WAN link between the DEFINITY and the Remote Office.

Setting up the Avaya R300

The following sections describe requirements and constraints that may affect the setup of
the Av aya R300 Remote Office Communicator.

DEFINITY Requirements

The main DEFINITY system may be a DEFINITY G3r, G3si, G3csi, DEFINITY One, or
IP 600. The main DEFINITY system must use DEFINITY Release 9 (R9) or newer
release software, and the Remote Office option enabled on the System-Parameters
Customer-Options screen. The DEFINITY cabinet housing the connection to the Avaya
R300 may be either a PPN (Processor Port Network) or an EPN (Expansion Port
Network).

In order for you to administer analog/digital stations and analog/digital trunks on the
A vaya R3 00, you must subs cribe to the approp riate Right to Use (RTU) software for these
telephony features members.

traffic is carried over the link between the Avaya R300 and the DEFINITY switch, but the
traffic is also based on the percent of calls shuffling. For more information about
shuffling, see ‘‘Shuffling’’ on page 24.

Number of terminals and trunks supported by the Avaya R300

Continued on next page

An individual Avaya R300 supports 26 stations (24 DCP and 2 Analog). For countries
which use 600 ohm impedances, the Avaya R300 also supports two 600 ohm loop-start
CO analog trunks. These two analog trunks support the feature of Emergency Transfer.
This feature enables a relay contact set to directly cut-through the tip and ring of the two
600 ohm analog station ports and to connect them to the two-wire analog trunk interface.
These two analog stations are operating in a loop-start trunk mode (for example, go
off-hook to seize an out-going CO trunk connection). Note that the DCP stations are not
operable in power failure mode. For this feature, the Emergency Transfer relay(s) are
operated either by a loss of power on the Avaya R300 Combo blade or by loss of
registration with the main switch, indicating loss of connectivity back to a main
DEFINITY site. This connectivity loss (could be the main ECS, WAN, LAN) will initiate
an emergency transfer within 60 seconds.

The following are the maximum number of DS0 trunks available:

■ 24 DS0 trunks available per T1 interface with robbed bit signaling (the Avaya

R300 supports a two-T1 model) or 23 with IDSN PRI T1.

■ 30 DS0 trunks per E1 trunk (the Avaya R300 supports a two-E1 model)

■ 2 DS0 trunks in another product model available per BRI trunk (the Avaya R300

supports a six-BRI model).

DEFINITY Enterprise Communication Server Release 9

The total number of DS0 trunks in a given configuration is determined by the number of
each type of trunk.

Types of terminals supported by the Avaya R300

The Av aya R300 can support DCP and analog phones directly and can support IP
Telephones and IP Softphones through its networking component. DCP and analog
phones (and other analog devices) can be connected directly through the Avaya R300
using the Interconnect unit. IP phones must be linked through a data switch or external

routing device from the Avaya R300’s Ethernet port.
The following tables describe the DCP and analog phones supported by the Avaya R300.

Avaya R300 Interconnect module

Each A vaya R300 will be supplied with one Avaya R300 Interconnect module which
provides an effective way to interconnect stations and trunks to the Avaya R300. Each
Interconnect module supports 24 DCP stations, 2 analog stations and 2 analog CO trunk
interfaces. Not all connections will be used for each ins tallation an d the CO tr unk s are n ot
supported in some countries.

The Interconnect module also supplies power to the Avaya R300’s Combo Blade to power
the DCP stations. Specifically, the Interconnect module provides 30W of -48VDC which

is used to provide the native “phantom” power for each DCP station (pins 4&5). If the a
Interconnect module is not used, the installation must provide “phantom” power for each
DCP station some other way (for example, 110-interconnect punch down using an Avaya
1145 or equivalent -48VDC power source).

The Avaya R300 Interconnect module provides auxiliary power to pins 7 and 8 for the 24
DCP connections so that a customer can use most auxiliary equipment without need or
concern for local power. This allows customers to use auxiliary equipment such as adjunct
speakerphones, headsets, and additional displays with auxiliary power already available.
Specifically, each DCP connection has a current limited auxiliary power of 6 Watts
(-48VDC). The yellow LED associated with the DCP modular jack will light, indicating a
warning condition, if more than 6 Watts of auxiliary power is drawn (indicating a short).

The following cabling is required for the Avaya R300 Interconnect module:

■ Power cord (appropriate for country of installatio n )

■ Cable to connect analog and DCP stations to the unit

Additionally, all network cable going to the Avaya R300 should be CAT 5 to provide the
best voice quality poss ible.

For more information about cabling with the Avaya R300, see MAX 3000 Basic
Installation and Configuration Guide, Appendix C, Cables and Connectors.

Wall field cabling

If you prefer to deploy the Avaya R300 with your existing wall field cabling, you can
connect the Combo Blade Y-cable to a conventional wall field panel. The Avaya R300
Combo Blade must be powered with the Y- cable or the Avaya R300 will not function. The
Y-cable has 50-pin, male and female connectors, which allows you to use standard,
Telcom 50-pin cables to extend the reach of the Y-cable to the wall field location. The
analog power plug has a gender changer, which makes the Y-cable compatible with
110-volt hardware.
