The Change Terr-Interface Menu brings up one of two screens depending on the interface card fitted:

Terr interface: 1:Electrical

2:Control Lines 3:Card specific

Change, Terr-Intfc Menu

Terr-Interface: Nothing to configure

with card fitted (YES)

Change, Terr-Intfc, Alternate Menu

If there are parameters to configure with the interface card fitted, then the options are:

ELECTRICAL For interface cards which support multiple electrical interfaces (eg currently P1440, P1441 and P1442 cards), this option allows the interface to be selected. For other cards the option may not be shown if the electrical interface cannot be changed.

CONTROL LINES This allows the interface control lines such as RTS and DTR to be configured. The operator has the option for each available control signal of ignoring the signal, or raising a Traffic Fault alarm if the interface control line goes `Off`.

CARD SPECIFIC Some interfaces such as 64 kbps G.703 have specific faults they can monitor (in the case of the 64 kbps G.703 interface it is the incoming octet timing), or options on the outgoing signal (supply outgoing octet timing or not). Control over such parameters is provided here.

With the standard P1440 (RS422, V.35, RS232, and optional G.703 interface) the following menu is shown (it may vary if other interfaces are used). The G.703 option on this screen is only shown if a T1 or E1 G.703 option is fitted.

Set electrical interface: [?]

1=V.35 2=RS422 3=RS232 4=G.703

The selection is self explanatory. Note that the 25 pin EIA 530 connector and 37 pin RS449 connectors on the rear of the equipment are connected in parallel, and both should not be used simultaneously. All electrical interfaces are available on both connectors, including G.703 unless it is an E1 G.703 option where the switch on the option card is set for 75 in which case the interface is on the BNC connectors fitted as part of this option.
