Atlas 890 System Controller Module (P/N 1200322L1); Quad T1/Pri Option Module (P/N 1200185L3); Quad E1/Pra Option Module (P/N 1200264L1); Quad Nx 56/64 Option Module (P/N 1200184L1) - ADTRAN ATLAS 800 SERIES System Manual

ATLAS 800 Series System Manual Option Modules Overview
System Description
Each option module provides a variety of performance and alarm status information. Several features of
each module are user-configurable, although default values reflect the most common configurations. All
option modules contain an extensive self-test as well as tests designed for the technologies they
incorporate.

ATLAS 890 System Controller Module (P/N 1200322L1)

In addition to controlling the shelf and its contents, the system controller modules serve as the user
interface. The user provisions and monitors all modules in the system, either locally or remotely, via the
system controller interface. The system controllers provision the option cards in the shelf via the faceplate
RJ-45 ADMIN connector of the active system controller and a VT100 terminal. Additionally, a
10/100BaseT Ethernet interface provides Telnet access.

Quad T1/PRI Option Module (P/N 1200185L3)

The Quad T1/PRI Option Module provides four channelized T1 or PRI interfaces. Each interface can
operate independently in DS-1, DSX-1, or PRI mode and any port can deliver timing for the system.

Quad E1/PRA Option Module (P/N 1200264L1)

The Quad E1/PRA Option Module provides four channelized E1 or PRA interfaces using the supplied
120-ohm, DB-15 converter cable. The Quad E1/PRA Option Module may also be purchased to include
BNC converter cables (P/N 4200264L1). This interface operates in CCS or CAS signaling mode and can
deliver timing for the system.

Quad Nx 56/64 Option Module (P/N 1200184L1)

The Quad Nx 56/64 Module provides four synchronous V.35 DTE ports (using the supplied DB-78 to V.35
converter cables) that can operate from 56K to 2.048 Mbps in steps of 56 or 64 kbps. Any port can deliver
timing for the system.

Quad USSI Option Module (P/N 4200261Lx)

The Quad USSI Option Module provides four synchronous DTE ports that can operate from 56K to
2.048 Mbps in steps of 56 or 64 kbps. Using adapter cables, the DTE ports available include EIA-530,
RS-449, RS-232, and CCITT X.21. Any port can deliver timing for the system.

Octal Basic Rate ISDN (U-Interface) Option Module (1200186L2)

The Octal Basic Rate ISDN Module provides eight Basic Rate ISDN (BRI) U interfaces, each capable of
operating in either NT or LT mode. Any port can deliver timing for the system.

Octal Basic Rate ISDN (S/T Interface) Option Module (1200343L1)

The Octal Basic Rate ISDN (S/T Interface) Module provides eight Basic Rate ISDN (BRI) S/T interfaces,
each capable of operating in NT (User Term) mode only. This module does not deliver timing for the
system.
