BASIC INFORMATION FOR ORDERING PRI ISDN LINES

ISDN Primary Rate is a communications service that allows the system to make up to 23

connections over a single line. It uses a 4-wire T1 line that carries 24 channels, each providing 64000

bps bandwidth. The service uses channels 1 to 23 as bearer (B) channels to carry connections

between two systems. The 24th channel is used for signaling information (the data link).

The customer should request the following options for a Primary Rate Line that is connected

directly to a CyberSWITCH:

• B8ZS encoding

• ESF framing

• all channels should be Circuit Switched Data

• Hunt Group (if desired)

• call bandwidth supported (56Kbps, 64Kbps, and/or 384Kbps)

• CLID (calling line Id); usually there is no charge for this

(CSU). If the line is provided by a LEC or IXC, the CSU is required by the phone company to protect

the phone network from any problems with customer premise equipment. At the time that the line
