How many B channels are included in an integrated services digital network (ISDN)
BRI?
A.
1
The cartridge needs to be replaced.
B.
2
The speakers are too close together.
C.
4
The turntable is plugged into an auxiliary port.
D.
23
SDN Primary Rate Interface (PRI) service offers 23 B channels and 1 D
channel in North Americaand Japan, yielding a total bit rate of 1.544 Mbps
(the PRI D channel runs at 64 kbps).ISDN PRI in Europe, Australia, and
other parts of the world provides 30 B channels plus one 64-kbps D channel
and a total interface rate of 2.048 Mbps.

Explanation:
The ISDN Basic Rate Interface (BRI) service offers two B channels and one D
channel (2B+D). BRI B-channel service operates at 64 kbps and is meant to
carry user data; BRI D-channel service operates at 16 kbps and is meant to
carry control and signaling information, although it can support user data
transmission under certain circumstances. The D channel signaling protocol
comprises Layers 1 through 3 of the OSI reference model. BRI also provides
for framing control and other overhead, bringing its total bit rate to 192
kbps.
