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.

Brief Description
D-Channel Backup with NFAS
When NFAS is used, a backup D-channel can be administered to improve 
reliability. The system switches to the backup D-channel if a signaling link failure 
occurs on the primary D-channel span.
One D-channel is administered as the Primary D-channel and another D-channel 
is administered as the...

Together, this pair of D-channels signals for all 70 (23+24+23) B-channels in the 
3 Primary Rate Interfaces.
Since the D-channels are signaling for more than one ISDN-PRI facility, 
D-Channel Backup requires the use of NFAS. At any given time, one of the two 
D-channels is carrying Layer 3 signaling messages, while the other D-channel...

Coordinate the following when implementing FAS and NFAS:
nDecide which T1/E1 facilities will use FAS.
nDecide which of the remaining T1/E1 facilities carries D-channel signaling 
information on the 16th (E1) or 24th (T1) channel. For those channels that 
have a D-Channel Backup, D-channel pairs...
