Paradyne 6800 manual Data Communications Equipment, Connecting Modems and DSUs

COMSPHERE 6800 Series Network Management System

Data Communications Equipment

This section explains how to connect the following data communications equipment to the host processor.

•DATAPHONE II modems, DSUs, and multiplexers

•COMSPHERE modems and DSUs

•ACCULINK multiplexers

There are two ways to connect these devices to the host processor:

•To connect modems and DSUs, use the control channels on the DCP/MUXi network monitor card(s) that was installed in the host processor.

•To connect multiplexers, use the serial ports on the IPC-1600 card in the host processor.

The modems and DSUs connect to the system using the control channels on the DCP/MUXi network monitor cards. The Altos 5000 platform comes with a single DCP/MUXi which supports eight control channels. An optional DCP/MUXi can be added for sixteen control channel support. Each control channel can connect up to 256 control devices and each control device monitors the health and status of its own network. A control channel can be collocated with the host processor or it can be remotely located via switched or private lines. The devices that can be connected to a control channel are categorized by service class:

•Analog Private Line (APL) Ð Individual or carrier-mounted modems connected to a control channel

•Digital Data Service (DDS) Ð Individual or carrier-mounted DSUs connected to a control channel

•Direct Distance Dialing (DDD) Ð Individual or carrier-mounted switched network modems connected to a control channel

The ACCULINK multiplexers connect directly to the host processor via the serial ports on the IPC-1600 card.

The following sections explain how to connect modems, DSUs, and ACCULINK multiplexers.

Connecting Modems and DSUs

The following devices all connect to the control channels on the DCP/MUXi card in the host processor:

•COMSPHERE 3400/4400 Series Model 2 APL modems

•COMSPHERE 3600 Series DSUs

•COMSPHERE 3800 Series DDD modems

•COMSPHERE 3900 Series APL modems

•DATAPHONE II APL and DDD modems

•DATAPHONE II DSUs
