Safety Warnings and Information

!
Modifying or tampering with PSAX chassis components may void your warranty. Any modification to this equipment not expressly authorized by Lucent Technologies may void your granted authority to operate such equipment.
!
When inserting modules into the chassis, slide them gently, not force­fully. Excessive force may cause the modules to be seated improperly in the chassis, and result in possible damage to the module or the chassis. Install or remove modules one at a time. Doing this aids in preventing the PSAX system from indicating any erroneous failure messages, and allows the PSAX system to reinitialize and display the accurate configu­ration of the module that is inserted.
!
Shipping the chassis with removable I/O, server, or CPU modules installed may cause damage to the chassis and the modules. Damage to any of the components in the system resulting from shipping the chassis with removable modules installed will void your warranty. Only Lucent­authorized personnel should ship the PSAX chassis with a module installed.

Safety Warnings and Information
When installing and operating the PacketStar® PSAX Multiservice Media Gateway, follow the safety guidelines provided below to help prevent serious personal injury and damage to the equipment. Please read all warnings and instructions supplied before beginning installation or configuration of the equipment. In addition to the general safety information provided below, you should also refer to the user and installation guides for other important safety information and procedures.

Electrostatic Discharge Precautions

The room where the PSAX system is located must have built-in precautions to provide protection from electrostatic discharge damage to electronic com­ponents. The following sections provide details on these necessary precau­tions.
Grounding Wrist Straps
Attach at least one grounding wrist strap to a common ground for each chas­sis/electronic rack to be handled. Follow these guidelines for wrist straps:
Make sure the wrist straps or wrist strap cords have built-in 1-megohm (minimum) resistance.
PacketStar® DSP2x Voice Server Modules User Guide, Issue 1 Release 8.0.0
iv 255-700-251
Make sure the wrist straps and wrist strap cords are UL listed.
Ensure the wrist strap cord is long enough so it can be worn while working
either at the front or the back of the rack.
Always discharge any static charge by touching your wrist strap before you touch the PSAX chassis.
Floor Covering
Be sure the room has an antistatic floor covering (conductive mat, tiles, or carpeting) to minimize static charge buildup as you walk across the room. Follow these guidelines for installing and maintaining proper floor coverings:
Using foot grounding straps (attached to the heels of your shoes) is recom­mended, even if you are walking in rooms with antistatic floor covering. These straps provide additional protection against electrostatic discharge. The straps should have built-in 1-megohm (minimum) resistance.
Wool carpet is not an acceptable floor covering.
Other types of carpet must be sprayed daily with a topical antistatic chemi-
cal before you perform any work in the room. Paying constant attention to carpet maintenance is time-consuming but required, if used.
Temperature and Humidity
Safety Warnings and Information
Establishing the proper temperature and humidity in the room where the PSAX system is located helps control many static discharge problems. Main­taining proper room climate is especially important when heat is turned on during the cold weather. To avoid damage to the PSAX system, do not allow the humidity to increase to the level where water droplets appear on sur­faces.
Clothing
When working with the PSAX system, avoid wearing clothing made from wool or synthetic materials. Try to minimize contact between clothing and electronic components.
Handling Chassis, Modules, and Components
Follow these guidelines for proper handling of the PSAX hardware to mini­mize electrostatic discharge damage:
Do not remove the chassis, modules, and other items from their protective packaging until you are ready to install them.
When installing modules and components, use a grounding wrist strap connected to a common electrical ground to prevent electrostatic discharge damage. (A common electrical ground is a complete circuit between a per­son or an electrical/electronic device and the earth.)
Store components in electrostatic-discharge-protective bags when they are not in use.

The high-performance midplane design supports 15 interface slots. In four segments, the unique PSAX 4500 midplane allows each segment to be scaled independently to provide nonblocking, redundant chassis bandwidths beyond 4.2 Gbps. Module protection for two groups of four or six multiport DS3, STS-1e, or E3 modules is provided via an N:1 protection scheme using rear access line interface modules. The protection module can fill in so that on the failure of any one of the modules in a group, traffic is maintained.
Using the latest voice-compression technology, the DSP2x Voice Server mod­ules deliver service providers eight times the capacity of traditional time divi­sion multiplex circuits while maintaining toll quality and reducing costs by nearly 30 percent per channel. A single PSAX 4500 system at the edge of the carrier network can transition traffic from a large number of network cus­tomers over high-speed DS1/E1 IMA, DS3/E3, OC-3, OC-3c/STM-1c, and OC-12c/STM-4c trunks into the ATM core, managing the whole quickly and efficiently, down to the individual permanent virtual circuit.

Module Placement

PacketStar® DSP2x Voice Server Modules User Guide, Issue 1 Release 8.0.0
255-700-251 2-11
Chapter 2 Modules Description

DSP2C Voice Server Module Software Features

Placement in the PSAX 4500 Chassis
Placement in Other PSAX Chassis
The DSP2D through DSP2F Voice Server modules are classified as high-speed modules when used in the PSAX 4500 chassis. To ensure that they operate at high speed, place them only with other high-speed modules in Segments 1–3 in the PSAX 4500. Placing the DSP2D, DSP2E, or DSP2F module in Segment 4 of the PSAX 4500 chassis will cause the module to operate at low speed, as Segment 4 contains the low-speed CPU2 module.
In the remaining PSAX chassis, any DSP2x Voice Server modules may be loaded in any I/O slot, but they require the CPU2 module if you are using System Software Release 7.1 and subsequent. If you are interfacing these modules with the Voice 2-Wire Station or Voice 2-Wire Office modules, you must use a CES module, such as the Enhanced DS1 or E1, running System Software Release version 7.1 or later.
DSP2C Voice Server Module Software Features

Emulated AlgoSets 2 and 3 on the DSP2C Module with Improved Features

Since System Software Release 6.2.0, the DSP2C Voice Server module has emulated the single-algoset modules for AlgoSet2 (formerly DSP2A mode), and AlgoSet3 (formerly DSP2B mode). These modules are emuluated on the DSP2C module with improved features. For a comparison of features among the three modules, see Table 2-1, entitled System Software Release 8.0 Voice Server Features and Table 2-5, in this chapter, and System Software Release
6.2.0 DSP2x Voice Server Features in this chapter.
With Software Release 6.3.0 and beyond, Lucent customers using the single­algoset DSP2A or the DSP2B Voice Server modules can not upgrade to the superior features offered by the DSP2C Voice Server module. (The single­algoset DSP2A and DSP2B modules were last upgraded in Release 6.2.0).
For instance, the Release 6.3.0 DSP2B mode configured on the DSP2C mod­ule offers 64 more voice compression channels than the single-algoset Release
6.2.0 DSP2B module. The DSP2B mode Echo Cancellation feature configured on the Release 6.3.0 DSP2C module supports twice the number of tails as on the Release 6.2.0 DSP2B single-algoset module.

DSP2C Fax Demodulation/Remodulation

Fax demodulation and remodulation is a more efficient way to transmit fax content. The DSP2C Voice Server module demodulates ITU V.17 fax signals at
14.4 Kbps, allowing baseband rates to use standard AAL2 fax packet formats and procedures of ITU-TI.366.2, Annex M. The demodulated fax calls use a maximum of 18 Kbps of bandwidth across the ATM network instead of tak­ing up a full 64 Kbps, a savings of up to 46 Kbps per call. If the ideal V.17 bandwidth is not available, the module can cycle through three other trans­mission options (V.29 at 9.6 Kbps; V.27 at 2.4 Kbps; and V.21 at 300 bps, in that order). Each uses less than the full 64 Kbps capacity for a fax call. The image data and associated control signals are remodulated at the remote ATM switch to voiceband for transmission to the peer fax. (Fax traffic that cannot be demodulated is transmitted at audio encoding suitable for voiceband data, that is, 64 Kbps).
PacketStar® DSP2x Voice Server Modules User Guide, Issue 1 Release 8.0.0
2-12 255-700-251
Chapter 2 Modules Description
DSP2C Voice Server Module Software Features
To use fax demodulation/remodulation, at least one digital signal processor (DSP) chip (or channel) on the DSP2C module must be configured for FaxRelayMode (AlgoSet4). A DSP channel’s capacity in this mode is four simultaneous fax calls. As fax calls will be processed only if resources (at least one FaxRelayMode-configured channel) are available, users should estimate the need for this mode based on how much fax traffic they send or receive and configure the DSP channels accordingly. The firmware automatically reroutes all incoming fax calls to channels configured for FaxRelayMode for processing. At the completion of the fax transmission, the connection is rerouted back to its original voice path. This frees the fax path for the next incoming fax call. If FaxRelayMode DSP resources are not available when a fax call arrives, due either to none being configured or to all the fax channels being occupied with other fax calls, the call is not rerouted. It will be pro­cessed according to available, enabled DSP voice processing options.
The tone detection mode is set on the CE-to-ATM VCC PVC Connection win­dow. See the DSP Tone Detection Modes and Associated Processing Performed table in Appendix A, Reference Tables, of the DSP2x Voice Server User Guide for details.
Figure 2-7 shows a logic flowchart of the decision process the firmware of the DSP2C module uses to reroute a fax call and Figure 2-8 for a sample configu­ration using the FaxRelayMode (AlgoSet4) feature.

DSP2x Voice Server Module Feature Details

Multiplexed or Nonmultiplexed AAL2

Lucent recommends multiplexing voice and data channels to reduce delay. Up to 64 trunk groups can be configured for multiplexing using ATM Adapta­tion Layer 2 (AAL2). AAL2 implementation is based on ITU-T Standards G.363, G.366.1, and G.366.2.
In nonmultiplexed voice and data processing, the payload length is a fixed value of 40 bytes, which results in a dramatic reduction of latency (40 msec end-to-end delay on the DSP2A, 60 msec end-to-end delay on the DSP2B, and 22 msec end-to-end delay on DSP2C-Echo Canceler). See Appendix A, Reference Tables, in this user guide for a comparison of standard AAL2 and nonmultiplexed AAL2 cells per second (cps) at each compression rate.

Dynamic DSP Resource Allocation

If a DSP fails on a DSP2x module, the connection admission control (CAC) in the primary CPU will reassign the connections passing through it to another DSP, if available. It will also move all the connections from an entire module, should it fail, to another DSP2 module, provided one is available and config­ured for the same voice processing parameters. (For example, a connection configured for 8 Kbps echo cancellaton will not re-route to a DSP configured for AlgoSet2).

255-700-251 2-17
Chapter 2 Modules Description
DSP2x Voice Server Module Feature Details

Failure Alarm

In Release 7.1 and subsequent, if a DSP chipset (channel) fails, the host pro­cessor in the module will attempt to reboot the chipset (channel) for seven consecutive attempts. If the channel does not reboot, it is classified as failed and the master CPU module is notified. DSP resource status can be viewed on the DSP Resource Table, accessible through the Site-Specific Menu by using the DSP Resource Configuration command.

Caller ID/Flash Hook Signalling

Caller ID frequency shift keying (FSK) information is transmitted between the first and second ring. This is valid when the called party is on-hook. Flash signals are transmitted over flash signaling-capable trunks to initiate internal calling features (i.e., Caller ID, call forwarding). As with FSK, the transmission of flash signalling is only valid when the called end of a line is off-hook. Flash signalling consists of signalling transitions from off-hook to on-hook to off-hook, where the on-hook state last between 300 msec and 1000 msec. This feature is compliant with TIA/EIA-464-B Requirements for Private Branch Exchange (PBX) Switching Equipment.
The DSP2A/B/C/D modules offer limited support to the Caller ID feature, but only with a specialized configuration setup with the Enhanced DS1 Module. See PacketStar PSAX Access Concentrator Caller ID Application Note (Document No. 255-700-006) for instructions on configuration.

Hybrid AlgoSet Configurations

The channels of the DSP2C and DSP2D Voice Server module are configurable in combinations of the AlgoSet voice processing modes; however, you are advised to read Chapter 3 of the DSP2x Voice Server Module User Guide for con­figuration cautions when using large numbers of DSP connections in com­plex networking environments with multiple trunk groups for voice, fax, and modem traffic in a PSAX chassis. On the DSP2D Voice Server, mixed AALx types are not supported.

OAM Support on the DSP2D Module

The DSP2D Voice Server module supports OAM on a per connection basis.

Previous System Software Release Version Compatibility

With software releases 6.2.0 and subsequent, modules all DSP2x modules will re-route connections made to failed DSPs. For modules previous to release 6.2.0, the DSP2A and DSP2B onboard processor cannot detect chip failures. The CPU can route connections that require DSP resources only if compatible DSP resources are available. For example, a connection config­ured for 8 Kbps echo cancellation will not re-route to a DSP configured for AlgoSet2.

Semi-Permanent Virtual Circuit Support

From Release 6.3.0 subsequent, the DSP2C can offer its voice and data pro­cessing capabilities in an SPVC over PNNI, ATM UNI, or IISP link. Up to 247 connections are configurable on a CE-to-ATM VCC PVC connection. See

Chapter 2 Modules Description

DSP2A and DSP2B Single-AlgoSet Voice Server Modules (System Release 6.2.0)

Chapter 8 for the console interface, and Chapter 9 for the AQueView EMS, in the DSP2x Voice Server Module User Guide for instructions and configuration constraints.
The DSP2C and DSP2D modules can process voice traffic on selected DS0 cir­cuits within the DS1 connections of the PSAX system. The DSP2C module supports AAL2 SVC connections and PVC multiplexing for reduced call latency. It also protects facsimile transmissions by automatically turning off voice processing and echo cancellation on any channel when it detects a modem tone.
Silence suppression saves bandwidth when there is no voice activity, and improves the user’s comfort by generating comfort noise when the line is silent. When there is no voice activity, the comfort noise feature samples the background noise and sends a few cells across the ATM link. These cells are fed into a white noise generator on the far end. The far end regenerates the background noise so that the user knows the connection is still active. The background noise level is updated every 5 seconds provided the background noise does not change. If the background does change, there is an activity burst and the background noise level is updated every 20 msec, until a steady state condition occurs again.

3 Maximizing DSP Resource Use on the DSP2C
Through DSP2F Voice Server Modules

Overview of This Chapter

Configuring and utilizing the resources of the DSP2x modules are, in general, relatively simple, but we recommend the procedural constraints described in this chapter to maximize module performance. These procedural constraints apply in complex networking environments in which there are multiple DSP2x modules, multiple trunk groups for voice, fax, and modem traffic, multiple packet sizes on varying interface protocols transmitting into and out of a PSAX chassis.

Procedural and Configuration Constraints

The constraints outlined in this chapter apply only to the standard AAL2 multiplexing mode of the DSP2C voice server module, not necessarily to the non-multiplexed AAL2 mode of the module.
Note: In this discussion, for the sake of clarity, the term “DSP refers to
any of the 32 hardware chips on the DSP2C module. The number of channels or connections that can be configured through a chip depends on the algorithm set (AlgoSet) chosen. Table 3-1 below describes the configuration modes available on the DSP2C Voice Server Module with System Software Release 7.0. Chapter 4 of this user guide contains specific instructions on configuring the chan­nels on the DPS2C module.

On the DSP2C Voice Server, the channels are configurable in any combination of voice processing AlgoSets 1 through 4, but it is not recommended. Please read the cautions in Chapter 3 of the DSP2x Voice Server Module User Guide when configuring large numbers of DSP connections in complex networking environments with multiple trunk groups for voice, fax, and modem traffic in a PSAX chassis.
This feature comes with full-time fax tone detection/bypass, a feature that is always turned on regardless of the AAL mode selected. The full-time fax tone detection/bypass is automatic and cannot be turned off by the user when echo-cancellation only mode is selected for the DSP2C (AlgoSet1), and the DSP2D (Algoset5).
This option is not supported in System Software Release 7.1 and subsequent on the DSP2D module, but is provided by Algoset6.
§
You can select the type of fax tone detection and subsequent firmware action you want on the CE-to­ATM DSP parameters connection windows. See the DSP Fax Tone Detection Modes Table in the Refer­ence Information Appendix in this guide for the four modes available.
See specific AAL2 configuration considerations in Chapter 7 and 8 of the appropriate Module User Guide.

Chapter 3 Maximizing DSP Resource Use on the DSP2C Through DSP2F Voice Server Modules

Engineering Planning

Engineering Planning
We highly recommended that you develop an engineering plan before provi­sioning the connections on the DSPs of each module. The plan should include these elements:
1. The number of DSP2C modules, which depends on the total number of trunk groups required, and the number of connections within each trunk group.
2. The addition of a few connections (or DSPs) to account for growth, even if they are not immediately needed or provisioned.
3. The number of trunk groups. Plan to assign each trunk group to a single DSP2C module. More than one trunk group can be assigned per module if the total connections of all trunk groups stay within the maximum capacity of 128 connections on the module. The type of information needed per trunk group should include:
~ The size of the trunk group (number of DS0 connections) ~ The type of voice processing for entire trunk group. Choose Algorithm
Set 2 (AlgoSet2), or Algorithm Set 3 (AlgoSet3). (Athough mixing of AlgoSet2 (DSP2A) and AlgoSet3 (DSP2B) voice processing modes on one DSP2C module is allowed, it is not recommended).
~ The number of fax relay connections needed by the trunk group. At least
one chip per DSP2C module must be configured for AlgoSet4 (fax relay mode) if the module is to process any incoming fax calls.

How the Module Firmware Handles Fax Calls

In the case of fax relay connections, when a fax call is detected and the call is transferred to a chip configured for AlgoSet4 (fax relay mode), the original voice processing chip is not free for use by any other call. The master CPU in the PSAX is not aware that the transfer has taken place. In effect, the call is using two DSP chip resources for one connection. The first is a permanent voice AlgoSet2 or AlgoSet3 connection, and the second is a temporary fax connection for the fax call. Once the number of fax relay mode (AlgoSet4) connections are assigned, subtract this number from the available connec­tions remaining (out of 128 total) on the given DSP2C module for assign­ment to pure voice processing connections. See Channel Reduction Avail­ability Caused by Fax Relay Connections vs. Voice Processing Connections on a DSP2C Module in the Reference Table appendix of the PacketStar Voice Server Modules User Guide, and your chassis User Guide(s), for details on the reduction of voice processing channel availability due to configuring DSP resources for fax relay mode service (AlgoSet4). ATM User-Network Inter­face Specification, Version 3.1, Cause Codes in the Reference Table appen­dix shows the tone detection settings available on the CE-to-ATM VCC PVC connection window.

Provisioning Rules

Provisioning Rules
Follow the rules below to provision the functions and connections of each DSP2C module.

Rule 1. Configure your largest AAL2 groups first.

Configure your largest AAL2 trunk groups first, and keep a record of each connection in each group, as it is assigned. This rule serves a dual purpose (see bullets below):
Configuring and adding your largest groups first assures that the CPU will process them in a locked cache (for example, one group of 224 channels in Echo Cancel mode). A locked cache assures that the host processor will not move data in and out of the cache. Data in a locked cache stays in the locked cache until it is processed out and sent on its way. While we have determined through testing that large AAL2 trunk groups (e.g., 224 con­nections) are processed with no problems, we nevertheless advise locked cache processing of large AAL2 trunk groups (more than 128 trunk group members).
Note: If you have large group(s) to configure, and the need for fax relay
on the same module, remember that at least one chip on the mod­ule must be configured for AlgoSet4 (fax relay mode). See Rule
3. To process fax calls, at least one channel must be configured as AlgoSet4 mode (fax relay).”).
If a problem develops with a particular connection, knowing where the connection originates and terminates should minimize the time spent on the troubleshooting process.
Rule 2. Configure as many connections as possible on one DSP2C module before configuring the next DSP2C module.
Configure one DSP2C module at a time, until either all its DSP resources and connections to those resources are either assigned or are left unassigned. (Although this is not an absolute imperative, it is recommended that at the initial setup of the CPU database, only one DSP2C module be configured). Assign or configure only those DSPs that will be needed according to your engineering plan. When you assign trunk group members to DSPs, keep in mind that all members of any one trunk group must fit on one module. You may not split the membership of any trunk group between DSP2C modules; that is, supposing you want to configure a trunk group of 224 echo cancel connections. You may not assign some members of this trunk group to one DSP2C module, and other members of the same trunk group to another DSP2C module. If you do so, when you attempt to add a connection of the CE-to-ATM VCC PVC Connection window, the CPU will return an error mes­sage DSP resources unavailable. See the Example Configuration Scenario: Connection Assignment Order Constraints for a detailed explanation of why the error message occurs.

Provisioning Rules

Rule 3. To process fax calls, at least one channel must be configured as AlgoSet4 mode (fax relay).

If fax relay mode is desired on any DSP2C module, at least DSP must be con­figured as fax relay (AlgoSet4). The following analogy helps explain why.
Think of the DSP2C as a building, which has 32 rooms (or DSP chips). The building has a capacity of at most 128 phone lines (four per DSP chip). Four of these phone lines run to each room in the building. Depending on the anticipated mix of fax users vs. voice users (which likely to be much less than half of all users), it is not prudent to assign a fax machine (i.e., a DSP chip with AlgoSet4) for each line in the building. Instead, it is best to assign a small number of the rooms for fax machines only (fax relay mode chipsets) and the remaining just for voice users. If five rooms (or chipsets) are assigned for fax on a given DSP2C server module, then:
5 chips X 4 channels per chip = 20 of the available phone line connections have been reserved for fax only.
In the other 27 rooms, the phone lines can be assigned for voice (either G.726-DSP2A mode or G.729-DSP2B mode). This means there are:
27 chips left X 4 channels per chip = 108 phone lines available for voice con­nections.
If a given DSP chip (for a given room) is set in either a AlgoSet2 or AlgoSet3 mode, and the voice user needs to make a fax call, the user connection must be transferred to one of the fax rooms (i.e., DSPs in AlgoSet4 [fax relay] mode). If there is an available fax machine (DSP chip set for fax mode), a fax call can be sent. If there is no available DSP in fax mode, then a fax call can­not be sent. After a user completes a fax call, the machine (i.e., a DSP chip in fax relay mode) is made available for another connection by another user who wishes to use it.
If fax relay mode service is to be supported for a portion of all user connec­tions, this design approach requires that a certain number of DSP chipsets on the DSP2C must be configured as fax relay mode. The number of chipsets depends on the expected fax traffic, as determined by the up front engineer­ing plan of expected user service demand for fax connections. The assign­ments of additional fax-configured chipsets on a DSP2C module will allow more fax calls but at the cost of reducing the number of DSPs that are avail­able for voice calls. These fax-configured chipsets are resources that are shared by all the remaining chipsets on a given DSP2C module. Recall from How the Module Firmware Handles Fax Calls that even when the call transfers to the fax-configured chip, the primary AlgoSet2/AlgoSet3 voice processing chips are still associated with the connection and cannot be used for new connections.
Rule 4. To maximize DSP2C resource performance, avoid mixing the DSP configuration modes on the same module.
You must understand that once two or more DSP2C modules are configured in a PSAX chassis, you have no direct control of how these resources are uti­lized by the master CPU in the PSAX as connections are added or deleted. Therefore, it is recommended that when using more than one DSP2C module

255-700-251 3-5
Chapter 3 Maximizing DSP Resource Use on the DSP2C Through DSP2F Voice Server Modules

Example Configuration Scenario: Connection Assignment Order Constraints

in a PSAX chassis, that a mix of AlgoSet2 (G.726 compression), AlgoSet3 (G.729a compression and G.729b silence suppression) and AlgoSet1 (Echo Cancel modes, G.165, G.168) not be used on the same module. Although it is possible to mix these compression and echo cancellation modes among sepa­rate DSP chips, due to the design of the CPU database in the PSAX, it is more straightforward procedurally to assign only one type of DSP compression mode for the entire module. This is due to how that the CPU database allows assignment of DSP resources and interface module connections. This assign­ment process involves knowledge of the order of configuration of these resources and knowledge of usage priorities for the DSP resources, which makes managing the CPU database complex. This rule applies to those remaining DSPs on a module that have not been configured for fax relay mode.

Rule 5. Understand and use the "modularity principle" for each DSP2C Algorithm Set.

If all connection resources on a given DSP2C chipset module are not fully assigned, there may be a need to establish dummy connections on any remaining available connection resources. This is due to the modularity of each DSP chip, which supports up to 4 connections each. Thus, if only 2 of the 4 connections on a DSP chip are unassigned, the unused 2 connections must be "dummied", that is, assigned to another E1/DS1 port before further provisioning can be done on another DSP2C module (see Example Configu­ration Scenario: Connection Assignment Order Constraints). Remember that not all DSP channels need to be assigned. If left unassigned, the CPU logic will allow provisioning of other DSP2C modules in the chassis.
Example Configuration Scenario: Connection Assignment Order Constraints
The following scenario illustrates Provisioning Rule 2, which prohibits split­ting a trunk group between two DSP2C modules. For simplicity, assume that fax relay mode is not used. Assume there are two DSP2C modules, both con­figured as AlgoSet3 (G.729a) mode, and standard AAL-2, for all DSP chipsets. Assume that two trunk groups of AAL-2 connections are to be set up using these DSP2C modules, Trunk Group A and Trunk Group B. Trunk Group A will have 100 connections, and Trunk Group B will have 40 connections. Since there are two DSP2C modules, there is a total resource of:
1 module X 4 connections per chipset X 32 chipsets = 128 connections per module
2 modules X 128 connections per module = 256 connections
As Trunk Group A is set up with the 100 connections, all the connections will be assigned to whichever DSP2C module was configured first (per Provision­ing Rule 2 above). One hundred connections use 25 chipsets on the module:
25 chipsets X 4 connections per chipset = 100 connections
Now there are 7 chipsets left on the module: 32 - 25 = 7
PacketStar® DSP2x Voice Server Modules User Guide, Issue 1 Release 8.0.0
3-6 255-700-251
Chapter 3 Maximizing DSP Resource Use on the DSP2C Through DSP2F Voice Server Modules
Example Configuration Scenario: Connection Assignment Order Constraints
Then Trunk Group B is set up with 40 connections. This will require 10 chipsets:
40 connections / 4 connections per chipset = 10 chipsets. You can see that this will involve splitting the second group of 40 connections between 2 modules.
On the CE-to-ATM VCC PVC connection window, when adding the first 28 Trunk Group B connections, (28/4 = 7, which will use the remaining 7 chipsets), each connection will be acknowledged as being added by the mas­ter CPU. They are assigned to remaining connection resources of the first DSP2C module.
When trying to add the 29th connection of Trunk Group B, however, it will be rejected and the system will say "DSP resources unavailable". The reason for this is that the CPU will attempt to put the 29th connection on the same module as the other connections having the the same virtual path indicator (VPI) and the same virtual channel indicator (VCI). (Remember that all trunk group members in the same group have the same VCI and VPI, see Figure 3-1). The CPU cannot do so, however, because the all DSP resources on that module are taken by all of Trunk Group A (100 connections), and the first 28 connections of Trunk Group B. The CPU, therefore, returns the error message.
Figure 3-1. AAL2 Trunking Architecture
If you desire to establish Trunk Group B (40 connections), the recommended procedure is to not assign any resources to the 7 unused DSP chipsets on the first module, that is, leave them unconfigured. This forces the CPU logic to move to additional DSP resource assignments to the next (second) DSP2C module, on which Trunk Group B can be assigned.

255-700-251 3-7
Chapter 3 Maximizing DSP Resource Use on the DSP2C Through DSP2F Voice Server Modules

Suggestion for Quicker Provisioning

Alternatively, one could temporarily assign 28 dummy connections on these remaining 7 DSP chipsets of the first DSP2C module using 8k compression to force the master CPU to start using the second DSP module. This is men­tioned in Rule 5 above. Then the additional 40 connections of Trunk Group B would be assigned to the second DSP2C module.
Only after making the Trunk Group B connections to the second DSP2C module resources, can you delete the 28 dummy connections on the first DSP2C module so as to free the ingress circuit emulation, egress ATM and DSP resources for use by other connections. Only when the remaining con­nections on the second DSP2C module are used, or left unassigned, will the CPU database allow further connection assignments on the first DSP2C mod­ule, or additional modules in the chassis.
Suggestion for Quicker Provisioning
An alternate suggestion to simplify provisioning on a given module is to con­figure the first DSP chipsets on the module (it must be chipset 1) in the mode desired for voice processing (either AlgoSet2 or AlgoSet3 mode). Then configure all remaining DSPs and they will take the properties of the first DSP. Then unassign a few DSPs at the end of the list and reconfigure them as fax relay, as needed. This process can save a lot of time.

Wireless Transport Configuration Considerations on the DSP2D Through DSP2F Voice Server Modules

Using AAL2 on the DSP2D Voice Server Module

On the DSP2D Voice Server module, the PSAX CPU will allow you to make up to 384 connections (8 per chip configured as AlgoSet6) on a VBR-to­ATM connection type. However, if you configure that number, the DSP2D will fail, as the module cannot handle 64 Kbps traffic per DS0 with a mixture of small and large packet sizes. Configure your packet sizes based on these known outcomes:
The module can process 96 DS0s sending 16 byte packets at 64 Kbps.
A small percentage of frames will be lost on 96 DS0s sending 256 byte
packets at 64 Kbps.
When configuring the AAL2 trunk, the IWF Type field on the AAL2 Trunk Connection Configuration window, should be set to None (the default) when you set up the AAL2 trunk group. Within this trunk you can mix voice (CE-to-ATM) and data (VBR-to-ATM).

Using AAL2 on the DSP2F Voice Server Module

On the DSP2F Voice Server module, the PSAX CPU will allow you to config­ure up to 672 connections (84 per chip configured as AlgoSet7) on VBR-to-ATM connections. However, if you configure that number, the DSP2F will fail, as the module cannot handle 64 Kbps traffic per DS0 with a mixture of small and large packet sizes.Configure your packet sizes based on these known outcomes:

3-8 255-700-251
Chapter 3 Maximizing DSP Resource Use on the DSP2C Through DSP2F Voice Server Modules
Wireless Transport Configuration Considerations on the DSP2D Through DSP2F Voice Server Modules
The module can process 672 DS0s sending 16 byte packets at 64 Kbps.
A small percentage of frames will be lost on 256 byte packets transmitted at
64 Kbps.
When configuring the AAL2 trunk, set the IWF Type field on the AAL2 Trunk Connection Configuration window to Packet-pipe. Within this trunk you cannot mix voice (CE-to-ATM) and data (VBR-to-ATM). For this type of connection, the DS0s can be strapped. Currently, the CAC is unaware of the strapping and uses the PCR of the VBR-to-ATM connection to determine the DSP load when less than 84 connections per chip are used. Using the config­ured PCR rate can cause the CPU to overload the DSP2F if the user does not configure the connection setups correctly.
DSP Chip Architecture and Connection Loads
Each chip configured as AlgoSet7 can support a maximum of 84 DS0s each at 64 Kbps with 16 byte packets. The data flow sequence is: Data in to DSP module from backplane –> DSP host processor –> DSP chip –> Back out through DSP host processor –> Out through Backplane to ATM module. (See Figure )The data passes through buffers before processing, in the host (pure voice) and also through the DSP chip buffer on its way in and out. The number of cells per second transmitting from the backplane to the DSP host processor will not match the cellsp per second exiting from the DSP chip back to the host. The cps exiting from the DSP chip varies greatly depending on a number of factors but primarily on the byte size of the packet.

Using AAL2 on the DSP2F Voice Server Module

On the DSP2E, configure the first six chips exactly like the DSP2D, and the last 2 chips exactly like the DSP2F.

Using the Console Interface

Overview of This Chapter

This chapter describes how to configure ports and channels for the DSP2x Voice Server modules, which is upgradable to PSAX system Release 8.0.0, and subsequent, on the PSAX system console interface. The configuration of the standalone single-algoset DSP2A and DSP2B modules follow this section (these modules are not upgradable beyond System Software Release 6.3.0).
To configure the DSP2x Voice Server modules, you must configure the DSP2 channels.

Configuring the Channels of the DSP2C, DSP2D, DSP2E, and DSP2F Voice Server Modules

The procedures and cautions for configuring the channels of the DSP2C through the DSP2F modules are the same, with these differences:
The DSP2C module has 32 channels (hardware chips); the DSP2D has 48 channels (chips)
The DSP2C provides AlgoSet1 through AlgoSet4 (algorithm sets).
The DSP2D provides AlgoSet1, 2, 3, 5, and 6.
The DSP2E provides AlgoSet6 and 7.
The DSP2F provides AlgoSet7.
You must configure the module before you can set up connections that use its features. To configure channels for the module, and to bring the channels into service, perform the steps in the following procedure.
Note: The channels and connections of the DSP2C Voice Server module
are configurable in any combination of the four AlgoSet voice pro­cessing modes; however, you are advised to read Chapter 3 of the DSP2x Voice Server Modules User Guide for configuration cautions when using large numbers of DSP connections in complex net­working environments with multiple trunk groups for voice, fax, and modem traffic in a PSAX chassis.
!
CAUTION:
Due to the copper wire interface between an Enhanced DS1 or E1 mod­ule with a PBX and/or key telephone system, the PSAX system and the other equipment should use a common chassis ground connection to avoid ground current loops, which could affect voice quality.

On the DSP2C Voice Server, the channels are configurable in any combination of voice processing AlgoSets 1 through 4, but it is not recommended. Please read the cautions in Chapter 3 of the DSP2x Voice Server Module User Guide when configuring large numbers of DSP connections in complex networking environments with multiple trunk groups for voice, fax, and modem traffic in a PSAX chassis.
This feature comes with full-time fax tone detection/bypass, a feature that is always turned on regardless of the AAL mode selected. The full-time fax tone detection/bypass is automatic and cannot be turned off by the user when echo-cancellation only mode is selected for the DSP2C (AlgoSet1), and the DSP2D (Algoset5).
This option is not supported in System Software Release 7.1 and subsequent on the DSP2D module, but is provided by Algoset6.
§
You can select the type of fax tone detection and subsequent firmware action you want on the CE-to­ATM DSP parameters connection windows. See the DSP Fax Tone Detection Modes Table in the Refer­ence Information Appendix in this guide for the four modes available.
See specific AAL2 configuration considerations in Chapter 7 and 8 of the appropriate Module User Guide.
