Warr anty Warnings
!
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 Multiservice Media Gateway system from indicating any
erroneous failure messages, and allows the Multiservice Media Gateway
system to reinitialize and display the accurate configuration of the
module that is inserted.
!
Shipping the chassis with removable 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 could void your warranty. Only Lucentauthorized personnel should ship the Multiservice Media Gateway
chassis with a module installed.

CS-03 Issue 8The Industry Canada label identifies certified equipment. This certification
means that the equipment meets certain telecommunications netwo rk
protective, operational, and safety requirements. The Department does not
guarantee that the equipment will operate to the user’s satisfaction.
Before installing this equipment, the user should ensure that it is permissible
to be connected to the facilities of the local telecommunications company.
The equipment must also be installed by using an acceptable method of
connection. In some cases, the company’s inside wiring associated with a
single-line individual service may be extended by means of a certified
connector assembly (telephone extension cord). The customer should be
aware that compliance with the above condition may not prevent
degradation of service in some situations.
Repairs to some certified equipment should be made by an authorized
maintenance facility designated by the supplier. Any repairs or alterations
made by the user to this equipment or equipment malfunctions might give
the telecommunications company caus e to request the user to disconnect the
equipment.
For their own protection, users should ensure that the ground connections of
the power utility , telephone lines, and internal metallic water pipe system are

Electroststic Discha rge Precautions
Electroststic Discharge Precautions
The room where the Multiservice Media Gateway 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-megaohm
(minimum) resistance.
•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 Multiservice Media Gateway 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. Thes e straps provide additional protection against electrostati c
discharge. The straps should have built-in 1-megaohm (minimum)
resistance.
•Wool carpet is not an acceptable floor covering.
•Other types of carpet must be sprayed daily with a topical antistatic
chemical before you perform any work in the room. Paying constant
attention to carpet maintenance is time-consuming but required, if used.
Temperature and Humidity
Establishing the proper temperature and humidity in the room where the
Multiservice Media Gateway 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
Multiservice Media Gateway system, do not allow the humidity to increase to
the level where water droplets appear on surfaces.

Chapter 1 Getting Started
Clothing
When working with the Multiservice Media Gateway system, avoid wearing
clothing made from wool or synthetic materials. Try to minimize contact
between clothing and electronic components.
Handling Multiservice Media Gateway System Components
Follow these guidelines for proper handling of the Multiservice Media
Gateway 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 electrost atic
discharge damage. (A common electrical ground is a complete circuit
between a person or an electrical/electr onic device and the earth.)
•Store components in electrostatic-discharge-protective bags when they
are not in use.

Overview of This Module
The 6-Port DS1 IMA module (see Figure 2-1) has six physical RJ-45 ports.
Inverse multiplexing over ATM permits a user to strap two to six of the
physical ports together to create ATM interfaces that support 3–9 Mbps of
bandwidth. A maximum of three IMA groups may be configured per module.
Source data enters the module from the backplane and is divided between
the ports within the IMA group specified in the virtual circuit connection.
The data leaves the front of the module and is transported across individual
T1 lines. At the destination IMA module, the T1 streams are merged back
together in correct order and passed on to other modules as directed by
virtual circuit connections. IMA dynamically handles conditions when T1s
within an IMA group become unavailable: the IMA "pipe" shrinks in
bandwidth to the remaining T1s and continues to pass traffic. When a
problem T1 comes back on line, the IMA "pipe" will enlarge to take full
advantage of the restored bandwidth.

3 Configuring Ports and Channels
Overview of This Chapter
This chapter describes how to set the values for the port and channel
configuration for the 6-Port DS1 IMA module using the PSAX Multiservice
Media Gateway system console interface.
Before You Begin
Be sure to complete the following actions first before configuring the 6-Port
DS1 IMA module:
•Configure your basic system (see "Configuring the System for Your Site"
in Chapter 4 of the appropriate PacketStar
Gateway user guide)
Using the Console
®
PSAX Multiservice Media
•Configure the Stratum 3–4 module (see "Configuring the Stratum 3–4
Module" in Chapter 4 of the appropriate PacketStar
Media Gateway user guide)
When configuring the 6-Port DS1 IMA module using the PSAX Multiservice
Media Gateway console, display-only fields are displayed with brackets.
The status line at the bottom of the console window gives instructions for the
field currently sel ect ed, and d i spl ays t rap me ssag es (s ee the ap p endi x of your
chassis user guide for a table of defined trap messages).
The configuration of the 6-Port DS1 IMA module involves the following
major tasks:
1. Each port must be configured with the I MA interface, and that IMA
interface must be brought into service.
2. Each IMA group must be established.
3. Each IMA group must be configured with an ATM interface (IISP, UNI,
or PNNI).
!
CAUTION:
When using a DSP2A, DSP2B, DSP2C, or DSP2D Voice Server module and
an Enhanced DS1 or E1 module with a PBX and/or key telephone system,
the Multiservice Media Gateway system and your equipment should use
a common chassis ground connection to avoid ground current loops,
which could affect voice quality.

Chapter 3 Configuring Ports and Channels Using the Console
Loopback Configuration Options
Loopback Configuration Options
To aid network troubleshooting and testing, loopback capability is provided
for the 6-Port DS1 IMA module. The loopback option on the module’s port
and channel configuration window for the module enables you to verify the
integrity of a port by transmitting a received signal back to the source.
Selecting a loopback option is described in the module configuration
procedure provided in this chapter.
If configuring a pair of 6-Port DS1 IMA module in the primary and standby
setup, the desired loopback option must be configured by the user on both
the primary and standby modules prior to bringing the pair into service. This
parameter is applied on a port-by-port basis on both the primary and standby
modules. If the line loop or local loop configuration is transferred from port A
on the primary module to port B on the standby module, the port parameter
does not transfer; it must be pre-configured on the standby by the user.
Figure 3-1 illustrates the line loop, payload loop, and local loop options.
Figure 3-1. Loopback Configuration Options on Certain I/O Modules
The following I/O modules have loopback capability:
•6-Port Enhanced DS1/T1 Multiservice module
•6-Port DS1 IMA module
•12-Port Medium-Density DS1 Multiservice module

configuration for the 6-Port DS1 IMA module using the AQueView
Management System (EMS).
Before You Begin
Be sure to complete the following actions first before configuring the 6-Port
DS1 IMA module:

CAUTION:
When using a DSP2A, DSP2B, DSP2C, or DSP2D Voice Server module and
an Enhanced DS1 or E1 module with a PBX and/or key telephone system,
the Multiservice Media Gateway system and your equipment should use
a common chassis ground connection to avoid ground current loops,
which could affect voice quality.
Loopback Configuration Options
To aid network troubleshooting and testing, loopback capability is provided
for the 6-Port DS1 IMA module. The loopback option on the module port
and channel configuration window for the module enables you to verify the
integrity of a port by transmitting a received signal back to the source.
Selecting a loopback option is described in Chapter 3.
PacketStar® PSAX 6-Port DS1 IMA Module User Guide, Issue1Release7.0
255-700-1664-1
Chapter 4 Configuring Ports and Channels Using the AQueView® System
Using the Right-Click Menu
If configuring a pair of 6-Port DS1 IMA module in the primary and standby
setup, the desired loopback option must be configured by the user on both
the primary and standby modules prior to bringing the pair into service. This
parameter is applied on a port-by-port basis on both the primary and standby
modules. If the line loop or local loop configuration is transferred from port A
on the primary module to port B on the standby module, the port parameter
does not transfer; it must be pre-configured on the standby by the user.
The following modules support line loop or local loop only if the standby is
preconfigured on a port-by-port basis:
•1-Port OC-3c 1+1 APS Multimode and Single-Mode modules
•1-Port STM-1 1+1 MSP Multimode and Single-Mode modules
•1-Port OC-12c/STM-4c 1+1 APS/MSP Multimode and Single-Mode
modules
Using the Right-Click Menu
You can perform various functions in the AQueV iew system by clicking the
right mouse button. This section describes the right-click menu options you
can use in the various windows in the AQueView system when configuring
ports and channels.

This state implies that the group has
accepted the far-end group parameters
and that the far-end has also accepted
its own group parameters, and does not
have sufficient links to move into the
Operational state. This state is excited
whe “sufficient links” can be moved
into the Active state.
BlockedThe group is blocked (e.g., inhibited by
the UM). The group can be blocked for
maintenance purposes while sufficient
links are Active in both directions.
The group is not inhibited and has sufficient links in both the Tx and Rx
directions. The IMA interface has now
the capability to receive ATM layer cells
and pass them from the IMA sublayer
to the ATM layer.
OperationalThe group is operat ional.

Overview of This Chapter
This chapter provides instructions for configuring the 6-Port DS1 IMA
module for the ATM IMA interface. Before you can set interface
configuration values, you must select an interface type value other than
Unconfigured in the Interface Type field on the DS1 IMA Port and Channel
Configuration window.
Note:Ports 1-6 of the 6-Port DS1 IMA module can be configured for
native DS1 ATM interfaces and for the ATM IMA interface.
However, when you configure a group (channel), you may
configure it for one of the following interfaces: ATM IISP User,
ATM IISP Network, ATM UNI 3.0, ATM UNI 3.1, ATM UNI 4.0 or
ATM PNNI 1.0.
For a matrix of modules and supporting interface types, see the Interface
Types by I/O Module Types Table in the Reference Tables appendix of your
PacketStar

PSAX User Guide.
the Console
Errors in Applying Interfaces to Ports
An error can occur when you apply an interface to a port or channel. If an
error condition occurs, the Multiservice Media Gateway sends an SNMP trap
that usually appears in the console Trap Log Display (accessible from the
Console Interface Main Menu window). The list below includes the most
common interface errors that cause the PSAX system to display a message.
(See the appendix, “SNMP Trap Messages,” for more information about the
SNMP traps related to interface errors).
•Entering values into fields that are outside of the configurable range of
values
•Attempting to configure an interface for a port or channel that has
already been configured
•Attempting to configure an interface that is already in service (must be
out of service to be configured or change field values)
•Entering field values that are not recognized by the PSAX system
software

ATM IMA Interface
This section provides instructions for configuring an I/O module for the ATM
Inverse Multiplexing over ATM (IMA) interface. You may configure the
following I/O modules for the ATM IMA interface:
•6-Port DS1 IMA module
•1-Port DS3 IMA module
•6-Port E1 IMA module
Automatic Use of IMA Links
In an IMA group, if one link is broken, the group can be configured to
automatically use the other links. For example, if an IMA group has three
DS1 links and one of the links fails, although the throughput will drop from
4.5 Mbps to 3.0 Mbps, the IMA group continues to work. If the slowest link
fails, there will be some cell loss on CBR connections as the other links speed
up their cell rate to eliminate excess delay, due to their buffering of cells.
IMA Configuration Considerations
Note:If your PSAX unit will be interoperating with a device that has
implemented ATM Forum IMA ATM Specification Version 1.0
such that its equipment incorrectly reports link states to the farend of an IMA connection, you must configure IMA groups with
the compatibility mode turned on. This also causes the PSAX unit to
correctly report link states and interoperate with your ATM
Forum IMA ATM Specification Version 1.0 equipment.
The following is a list of operations considerations for the IMA interface:
•Once an IMA group has been deleted, its status is displayed as
"Insufficient-Links."
•Links may not be added or removed from a group that is configured. You
must delete any existing interfaces applied to the group before adding or
removing links.
•Operational Status refers to IMA group status, which can be viewed in
the port and channel configuration window.
~ You can restart an IMA group by taking it administratively out of
service and then bringing it back into service.
~ In order to change any group configuration parameters, the group
must be completely unconfigured.
~ There may be difficulties if the IMA group is configured for symetric
operation but has asymetric link delays. For example, one end may
consider links A, B, and C to have problems, while the other end
considers D, E, and F to have problems.
~ Four configurable transmit frame lengths are provided: 32, 64, 128,
256 cells. One ICP (IMA communication protocol) cell is sent over
each link once per IMA frame. If you select a larger frame length,
PacketStar® PSAX 6-Port DS1 IMA Module User Guide, Issue1Release7.0
5-2 255-700-166
there will be less overhead. If you select a smaller frame length, the
IMA group has better response in communications with the far end,
resulting in faster error detection and recovery. The IMA specification
only requires equipment to support a frame length of 128. If a frame
length other than 128 is configured and the far-end is connected to
equipment that doesn’t support it, the far-end group enters the configabort state.
~ The IMA identifier (ID) is an 8-bit (0-255) identifier for this IMA
group. There is no significance to any particular values of IMA IDs.
Since the IMA ID is used to identify a group to the far-end, pick a
unique value instead of leaving it as the default of 0.
Accessing the ATM IMA Interface
If you selected the value AtmIma as the interface type, the ATM IMA
Interface Configuration window (see Figure 5-1) is displayed.

NotInGroup Interface is not assigned to a group.
UnusableNo-
Does not work; non-specific reason.
Reason
Unusable FaultLocal failure status of a link belonging to an
IMA group (not currently supported.)
The PSAX device does not generate this con-
dition, but may report such a condition generated by the far end of an IMA connection.
Unusable
Misconnected
An IMA link is not corrected to the proper
end. (The PSAX device does not currently
generate this condition, but the PSAX device
reports this condition to the user if the far-end
reports it to the PSAX device.)
For example, when an IMA group is established, the links immediately discover which
device they are connecting to on the far end.
If cables are then removed and plugged back
in differently , then the equipment may signify
that it is misconnected.
Unusable Inhibited
This is an administrative mechanism for taking an IMA link out of service. When in this
state, it is unknown whether there are any
physical problems with the link.
Unusable Failed Check the defect value displayed.
UsableThere are no local reasons why this link is not
active. The only thing preventing it from
being active is the far-end state (for example,
a transmitter cannot be active and send real
data until the far-end receiver is ready to
accept that data).

Interim Interswitch Signaling Protocol (IISP), formerly known as PNNI Phase
0, was introduced as an interim standard, pending completion of the PNNI
Phase 1. Building on ATM UNI 3.0 and ATM UNI 3.1, it uses static routing
tables established by the network administrator to route connections around
link failures.
The IISP interface requires the default range of values 0–255 for the virtual
path identifier (VPI) and 32–255 for the virtual channel identifier (VCI) to
accept and establish calls. This value is set on the ATM IISP Interface
Configuration window.
Each connection using the IISP interface is configurable as either the user
side or the network side.
Optimizing SVC Call Performance
The service-specific connection-oriented protocol (SSCOP) field is set on
these interface configuration windows: ATM IISP network or IISP user, ATM
UNI 3.0 or UNI 3.1, or ATM PNNI 1.0.
Note:These settings are suggested for connecting to a Multiservice
Media Gateway from a remote site only. The Multiservice Media
Gateway configures these settings internally in its own ATM
switch.
When there are unacknowledged protocol data units (PDUs), the MaxPD
field on the remote end peer (such as the NavisCore
PacketStar® PSAX 6-Port DS1 IMA Module User Guide, Issue1Release7.0
5-6 255-700-166
™
CBX 500™) shows the
maximum number of SSCOP transmitted since the last PSAX polling of the
peer. To optimize call performance, the SSCOP Rx Window Size field of the
local ATM interface should be less than the maximum value displayed in the
MaxPD credit window at the remote end of the ATM interface. Otherwise,
the rate at which switched calls can be set and released may be degraded.
On the ATM IISP Interface Configuration window, the maximum credit
window (the SSCOP Rx Window Size field) is configurable for a value up to
32 for all ATM interfaces on the Multiservice Media Gateway. The interfaces
of the ATM switches that are connected to an Multiservice Media Gateway
should be configured to the same values. This results in 100% call
completion at a call setup rate of 60 calls per second using even distribution.
If these values are not configured in this way, calls will be set up at a rate of
less than 60 calls per second.
Note:Vari ous SSCOP paramete r setti ngs deter mine th e maximum c redit
window. As a result, you may not be able to directly use these
settings.
