Chapter 2. Installation

DBU and Voice Interface Card Slots

The FSU 5622 ESP rear panel has two card slots for the installa-

tion of dial backup and voice interface cards. To insert cards,

perform the following procedure:

1. Remove power from the FSU 5622 ESP.

2. Slide the card into the corresponding rear slot until the card

panel is flush with the FSU 5622 ESP chassis.

3. Push card locks in (until they click) to secure the card and

ensure proper installation.

Card slots are keyed to prevent improper installation (i.e., putting a

DBU card into the voice slot).

Telco Connector

The TELCO connector is an eight-position modular jack which

provides connection to a dedicated 56/64 kbps network. See the

appendix Pinouts for the TELCO connector's pin assignments.

Control Port

The eight-position modular jack labeled CONTROL provides

connection to a VT 100 EIA-232 compatible interface. This

enables the FSU 5622 ESP to be configured through a terminal

instead of the front panel. Use the VT 100 terminal cable (pro-

vided) for this connection. See the appendix Pinouts for the

connector pin assignments. A description of the operation of this

port is covered in the chapter Operation.

DTE Connectors

DTE devices are connected to the DTE connectors using either an

EIA-232 DTE cable or an ADTRAN V.35 DTE adapter cable. The

maximum cable lengths recommended are 50 feet for the EIA-

232 and 100 feet for the V.35. The pin assignments are listed in

the appendix Pinouts.
