USER MODULES

This section provides description about the modules/components that can be installed by the user.

LINE CARDS

All the line cards can be mounted on a single slot except the SE card, which requires two slots. Next generation SE line cards may occupy a single slot only. An overview of the line cards is given below.

SERVICES ENGINE

The SE card is the main data processing center in the chassis. The SE card has two external auto-negotiable copper GigE ports. The GigE interfaces can autonegotiate, transmit, and receive data packets at the rate of 10/100/1000 Mbps.

The LEDs on the SE card indicate Active or Fault conditions. The LEDs on the Gigabit Ethernet ports of the SE card indicate Link Status, Link Speed, and Activity. The SE card is a dual slot line card, and is installed in slots 2, 3.

OmniAccess 740 Overview

SERIAL LINE CARD (V.35/X.21)

Serial Card (V.35/X.21) provides WAN termination for four ports over serial sync interfaces. The card is a single slot line card, and is installed either in slot 0 or 1. The card allows full duplex operation on a single copper pair and operates in either DTE of DCE mode depending on the cable attached.

V.35 and X.21 are well known communication protocols over synchronous serial lines.

V.35 Interface

The V.35 interface was originally specified by CCITT as an interface for 48kbps line transmissions. It has been adopted for all line speeds above 20kbps.

V.35 is a mixture of balanced and common earth signal interfaces. The control lines including DTR, DSR. DCD, RTS, and CTS are single wire common earth interfaces. The data and clock signals are balanced signals.

X.21 Interface

The physical interface between the DTE and the DCE is defined in ITU-T recommendation as X.21. The DCE provides a full-duplex, bit-serial, synchronous transmission path between the DTE and the local PSE. It can operate at data rates from 600bps.
