ISDN-BRI
Integrated Service Digital Network – Basic Rate Interface (ISDN-BRI) is a Public
Switched Telephone Network (PSTN) service that provides two B channels and a D
channel (2B + D) for voice call trunking. The B channels provide two voice path
connections. Caller ID is usually a standard feature on ISDN-BRI provided trunks.
Caller ID indication displays the calling party telephone number on the LCD of the
multiline terminal for CO incoming calls. This interface provides voice communication
path only.
ISDN-PRI

Switched Telephone Network (PSTN) service that provides 23 B channels and a
single D channel (23B+1D) for trunking. The UNIVERGE SV8100 supports it. Caller
