CHAPTER 1 GENERAL INFORMATION

System Outline

DTI

The Digital Trunk Interf ac e (DTI) i nterfaces the PBX directly to 24/30-channel PCM transmission

line. The DTI has the following functions:

For 24DT I:

• Unipolar/Bipolar Conversion (AMI Format/B8ZS Format)

• Alarm Detection/Insertion

• Digital PAD on Voice Signal Transmission

• Loop-Back Test (Local/Remote Loop Back)

• Cyclic Redundancy Checking (based on ITU-T Rec. G704)

For 30DT I:

• Unipolar/Bipolar Conversion (HDB3 Format)

• Alarm Detection/Insertion

• Digital PAD on Voice Signal Transmission

• Cyclic Redundancy Checking (based on ITU-T Rec. G704)

For connections of a 24DTI and transmission line, twisted -pair cable ca n be used. F or connection

of a 30DTI and transmission line, either coaxial cable or twiste d-pair cable can be used.

DCH

The D Channel Handler (DCH) provides the D Channel signalling interface through the DTI to an

ISDN exchange, and it is responsible for signaling between the PBX and the I SDN exchange

under control of the system MP.

PRT

The Primary Rate Interface Trunk (PRT) provides the ISDN Primary Rate Interface (1.5 Mbps

PCM-23B + D) and a built-in DCH. The PRT has the following functions:

• Unipolar/Bipolar Conversion (AMI Format/B8ZS Format)

• Alarm Detection/Insertion

• Digital PAD on Voice Signal Transmission

• Loop-Back Test (Local/Remote Loop Back)

• Cyclic Redundancy Checking (based on ITU-T Rec. G704)

For connections of PRT and transmission line, twisted-pair cable can be use d.

NOTE: ISDN requires B8ZS line coding with Extended Superframing (ESF) For mat.
