Menu Option 9 Configuring the span line’s signaling channel

If using non-facility associated signaling (NFAS), configure a B- or

D-channel for signaling purposes.

Menu Option 10 Configuring the span line’s interface ID

If using NFAS, configure the interface ID specified by the Telco with this option.

The default is 0 for non-NFAS.

Menu Option 11 Configuring span level call-type blocking

Span level call-type blocking allows specific types of calls to be rejected when placed on the span.

Configure the call-type blocking feature for one of these:

■All calls (analog and digital) blocked

■Analog calls blocked

■Digital calls blocked

■No calls blocked

Any changes made will take affect on the next call.

Menu Option 12 Configuring span level cause codes

When calls are rejected at the span level, configure a cause code to be transmitted to the Telco.
