Emergency Transfer panels are available in multiples of five telephones, which 
may be pulse-dialing or touch-tone phones. You must use pulse dialing if the CO 
accepts dial pulses only. Each telephone can be connected to a separate CO.
When your system is not in Emergency Transfer mode, transfer phones can be 
used as regular...

If you are operating in a Distributed Communications System (DCS) 
environment, you need to assign a different telecommuting-access extension to 
each switch and tell your users which extension they should use. You can use 
Extended User Administration of Redirected Calls from any of the DCS nodes, 
but you need to dial the...

How to use from an off-site location
To use Extended User Administration of Redirected Calls from off-site, you must 
first access the telecommuting-access extension. If you make the request via 
Direct Inward Dialing (DID), you must precede the extension with the correct 
public-network prefix. If you make the request via a trunk...

nCall Coverage
Extended User Administration of Redirected Calls interacts with this 
feature only in that system users can change their lead-coverage path.
An attempt to activate Send All Calls is denied if the currently active 
coverage path does not allow Send All Calls in its coverage criteria. 
However, if you activate Send All...

Facility and Non-Facility Associated 
Signaling
Facility Associated Signaling (FAS) allows an ISDN-PRI T1/E1 interface 
D-channel to carry signaling information for all the bearer (B) channels on its 
associated span.
Non-Facility Associated Signaling (NFAS) allows 1 ISDN-PRI T1/E1 interface 
D-channel to carry signaling information for...

With T1 (24 channel) interfaces, 2 of the ISDN-PRIs contain a D-channel and 23 
B-channels, while the other ISDN-PRI contains 24 B-channels. One of the 
D-channels is the Primary D-channel, and the other is the Secondary D-channel. 
Together, this pair of D-channels signals for all 70 (23+24+23) B-channels in the 
3 Primary Rate...

D-Channel Backup activation
nD-Channel Failure
If the signaling link fails on the active D-channel (D1) or the hardware 
carrying D1 fails, the system sends a message over the standby D-channel 
(D2). D2 then becomes the active D-channel and carries all subsequent 
signaling messages. When the signaling link or hardware on D1 recovers...

nDefine Signaling Groups. A Signaling Group is a group of B-channels for 
which a given D-channel (or D-channel pair) carries the signaling 
information. Each Signaling Group must be designated as either a FAS or 
NFAS Signaling Group.
— A FAS Signaling Group must contain all the ISDN B-Channels on 
the T1/E1 interface associated with...

The Signaling Mode field must be specified for each DS1 circuit pack. Because 
this circuit pack has the Signaling Mode field set to isdn-ext, all trunks on this 
circuit pack are signaled using either inband robbed-bit signaling or a D-channel 
on another DS1 circuit pack.

Next, Signaling Groups are...
