Purpose of This Guide
The PacketStar®PSAX 1-Port Channelized OC-3/STM-1 CES Module User Guide
provides a description of the 1-Port Channelized OC-3/STM-1 CES. It also
provides information on how to configure the module ports and channels.
The PacketStar®PSAX 1-Port Channelized OC-3/STM-1 CES Module User Guide
provides a description of the 1-Port Channelized OC-3/STM-1 CES modules
(23N12 (MM)/23N13 (SM)). It also provides information on how to config-
ure the module ports and channels.
For information on configuring interfaces and provisioning connections
through the PSAX console interface, see the PacketStar®PSAX Connections Pro-
visioning Guide. If the Navis®EMS-PSAX interface is being used, see the
Navis®EMS-PSAX Interface and Connection Provisioning Guide.
Note: If you are using this module for the first time, you should read
through this guide in its entirety before beginning the configura-
tion process. The chapters in this guide are arranged in the logical
order of normal configuration and should be performed in that
order for the module to operate successfully.
Audience for This Guide
The information in this guide is intended for users who will configure ports
and channels for the 1-Port Channelized OC-3/STM-1 CES modules, in the
PSAX Multiservice Media Gateway system.

About the PacketStar PSAX Product Family
PSAX 1000 Multiservice Media Gateway
The PacketStar PSAX 1000 Multiservice Media Gateway is designed to provide
a full range of central office-based multiservice media gateway functions in a
small, competitively-priced package suitable for customer premise deploy-
ment. Ideal for central office, large enterprise, or wireless cell site multiser-
vice media gateway applications, the PSAX 1000 system provides highly reli-
able network access for time-division multiplex voice, frame relay,
10/100BASE-T Ethernet, and ATM data applications.
When it is functioning in a redundant operating mode and after it has experi-
enced a single-point failure, the PSAX 1000 system provides up to 630 Mbps
of ATM cell bus capacity. The total ATM cell bus capacity of the system may
also be scaled to provide nonblocking, nonredundant chassis bandwidths
beyond 630 Mbps.
Supporting up to five slots (19–inch chassis) for I/O and server mod-
ules—with a full range of interfaces such as DS0A, DS1/E1, DS3/E3, OC-3,
OC-3c/STM-1, OC-12c/STM-4c, 10/100BASE-T Ethernet, and serial—the
PSAX 1000 system is a cost-effective access switch solution for connecting to
legacy equipment.
PSAX 1250 Multiservice Media Gateway
The PacketStar PSAX 1250 Multiservice Media Gateway is designed to provide
a full range of central office-based multiservice ATM access functions. Ideal
for the central office or a large enterprise’s multiservice media gateway, the
PSAX 1250 system provides highly reliable network access for time-division
multiplex voice, frame relay, 10/100BASE-T Ethernet, and ATM data applica-
tions.
When it is functioning in a redundant operating mode and after it has experi-
enced a single-point failure, the PSAX 1250 system provides up to 600 Mbps
of ATM cell bus capacity. The total ATM cell bus capacity of the system may
also be scaled to provide nonblocking, nonredundant chassis bandwidths
beyond 600 Mbps.
Supporting 10 slots (19-inch chassis) or 14 slots (23-inch chassis) for I/O and
server modules—with a full range of interfaces such as DS0A, DS1/E1,
DS3/E3, OC-3, OC-3c/STM-1, OC-12c/STM-4c, 10/100BASE-T Ethernet,
and serial—the PSAX 1250 system is a cost-effective access switch solution
for interworking with legacy equipment.
PSAX 2300 Multiservice Media Gateway
The PacketStar PSAX 2300 Multiservice Media Gateway offers carrier-grade,
high-density multiservice ATM access functions. Designed as the multiservice
media gateway for the central office or for a large enterprise customer, the
PSAX 2300 system provides network access for time-division multiplex
voice, frame relay, 10/100BASE-T Ethernet, and ATM data applications.

When it is functioning in a redundant operating mode and after it has experi-
enced a single-point failure, the PSAX 2300 system provides up to 1.9 Gbps
of ATM cell bus capacity. The total ATM cell bus capacity of the system may
also be scaled to provide nonblocking, nonredundant chassis bandwidths
beyond 1.9 Gbps.
Supporting 15 slots for I/O and server modules—with provisions for OC-3,
OC-3c/STM-1, and OC-12c/STM-4c interfaces with 1:1 protection, 1:1 DS1
module protection switching, and a full range of interfaces such as DS0A,
DS1/E1, DS3/E3, 10/100BASE-T Ethernet, and serial—the PSAX 2300 sys-
tem solves demanding and diverse network design challenges with ease.
PSAX 4500 Multiservice Media Gateway
The PacketStar PSAX 4500 Multiservice Media Gateway provides carrier-class
reliability, with an unmatched range of service capabilities, end-to-end traffic
prioritization, “any-service, any-channel” flexibility, and breakthrough voice
technology. Ideal for the central office or a large enterprise multiservice
media gateway, the PSAX 4500 system provides highly reliable network
access for time-division multiplex voice, frame relay, 10/100BASE-T Ether-
net, and ATM data applications.
When it is functioning in a redundant operating mode and after it has experi-
enced a single-point failure, the PSAX 4500 system provides up to 4.2 Gbps
of ATM cell bus capacity. The total ATM cell bus capacity of the system may
also be scaled to provide nonblocking, nonredundant chassis bandwidths
beyond 4.2 Gbps.
The high-performance midplane design supports 15 interface slots. Module
protection for two groups of four or six multiport DS3, STS-1e, or E3 mod-
ules is provided via an N:1 protection scheme using rear access line interface
modules. The protection module provides backup so that on the failure of
any one of the modules in a group, traffic is maintained. 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-4c, and OC-12c/STM-4c trunks into the ATM core, managing
the whole quickly and efficiently, down to the individual permanent virtual
circuit.
Through the use of the latest DSP voice technology, the PSAX 4500 system
supports advanced voice traffic over ATM (VToA) services for up to 6048 DS0
channels. As a multiservice media gateway—with H.248 call control, CAS,
PRI, GR-303, and V5.2 protocols, 3-Port DS3/STS-1e, 1-Port OC-3/STM-1
CES, and Tones and Announcements modules—the PSAX 4500 system pro-
vides packet solutions for voice over xDSL, trunking, tandem, and PRI offload
switching.

Use of Field Description Tables
For all illustrations for configuration windows in this guide for both the
PSAX system console interface and the EMS-PSAX, the field description
tables normally follow the command description tables. Field description
tables define the editable and the display-only fields, their functions, valid
values, and constraints, if applicable. As in the command description tables,
the Note: text convention is also used, where appropriate, in the field descrip-
tion tables to alert the user to special instructions or configuration constraints
(see Figure 1-1).
