ISL maintenance
Overview
This chapter provides a DCHI reference list of D-channel commands, an technical document
reference for maintenance messages, and maintenance testing information.
This chapter provides the information required to implement ISL on the system including:
• hardware and software installation
• implementation of components needed to provide basic call service
ISDN features are treated separately in the chapter devoted to ISDN feature
implementation.
This chapter assumes that ESN implementation is already in place. It also assumes that the
reader has a basic understanding of NARS and CDP.
Two modes of ISL are available: shared and dedicated. This chapter covers ISL installation in
dedicated mode using dedicated and leased lines. Shared mode installations are done
according to the instructions supplied for PRI, with the noted exceptions.

ISL, regardless of the operation mode, uses analogue or digital TIE lines as B-channels.
