DATASHEET

Product Description

The Juniper Networks® dual-port and quad-port T1/E1 Gigabit-Backplane Physical Interface

Modules (GPIMs) provide the physical connection to T1 or E1 network media types and include

integrated CSU/DSU. Juniper’s dual-port and quad-port T1/E1 GPIMs forward packets for

processing and at the same time perform framing and line-speed signaling.

Features and Beneﬁts

Juniper’s dual-port or quad-port T1/E1 GPIMs provide the following benefits:

• Dual-port form factor that provides high density for broadly deployed T1/E1 network

connections, while making effective use of the Juniper Networks SRX650 Services

Gateway modular interface slots

• Integrated CSU/DSU that eliminates the need to deploy a separate external device,

saving valuable space and simplifying management

Features

The quad-port and dual-port T1/E1 Gigabit-Backplane Physical Interface Module (GPIM)

provides the following common key features for both T1 and E1 modes:

• Integrated CSU/DSU to eliminate the need for a separate external device

• Supports fractional T1/E1 connections in both 56 Kbps and 64 Kbps operating modes

• Independent internal and external clocking option

• Alarm reporting with a 24-hour history maintained

• Loopback (local and remote) and bit error rate test/pseudo-random binary sequence

(BERT/PRBS) diagnostics

• Multilink Frame Relay and Multilink Point-to-Point Protocol (PPP) support

• MTU size of 9,000 bytes (maximum)

Product Overview

Dual-port and quad-port T1/E1 GPIMs

are used with the Juniper Networks

SRX650 Services Gateway, providing

high density for broadly deployed T1/

E1 network connections while making

eective use of the SRX650 modular

interface slots. Integrated channel

service unit/data service unit (CSU/

DSU) eliminates the need to deploy

a separate external device, saving

valuable space and simplifying

management.
