AT&T 585-310-231 manual 6Issue 2.0 December

■Add-on serial ports (ttyaa through ttyah) on a Multi-Port Serial Card are used for the third and subsequent device.

■The preferred order of connection of the devices is:

—MERLIN LEGEND administration

—optional Remote Maintenance M odem

—optional Call A ccounting System (SMDR)

—optional customer remote access terminals or modems

If the MERLIN LEGEND system is within 50 feet (15 meters) of the Intuity system, and the MERLIN LEGEND system and the Intuity system share the same power outlet, a direct connection can be made between the MERLIN LEGEND administration and optional SMDR ports and the Intuity system ports.

If the MERLIN LEGEND system is farther than 50 feet (15 meters) from the Intuity system, or the MERLIN LEGEND system and the Intuity system do not share the same power outlet, data cables from the MERLIN LEGEND system administration and optional SMDR ports to the Intuity system ports have to be extended with Z3A2 ADU cable drivers. Two Z3A2 ADU interface units are required for each cable, one at each end.

The optional Remote Maintenance Modem must be co-located with the Intuity system processor and must be connected to Serial Port 2.

Optional customer access terminals may be co-located with the Intuity system processor and directly connected to the next available serial port, or one or more modems may be connected to the next available serial port(s) for dial-in access.

Connecting Administration Ports

Within 50 feet, Same Power Outlet

This method is used only when the MERLIN LEGEND Communications System and the Intuity system are within 50 feet and share the same power outlet.

The following parts are required:

■DB-9S to DB-25P Adapter (MAP/40 and MAP/100 only)

■355AF Adapter

■D8W-87 Modular Cord

Refer to Figure 4-3.Connect the MERLIN LEGEND Communications System Admin port and the Intuity system Serial Port 1 (COM1) by following these steps:

1.Connect one end of a D8W-87 modular cord to the Admin (lower) jack of the MERLIN LEGEND Communications System.

2.Connect the other end of the D8W-87 modular cord to a 355AF adapter.
