[asterisk-users] Sangoma A104d and Adtran 850 problems

[Lyle Giese]

A channel bank != PRI. A PRI is ISDN. A channel bank is not the same as
a Primary rate ISDN line.

With a channel bank, each channel's signaling is done in the channel.
Primary rate ISDN has a D channel to contain all signalling for the 23
voice channels, taking over the 24th voice channel.
