ISL Implementation and Maintenance
This chapter provides the information needed to implement ISL on the
Meridian 1 Option 11C system including:
• hardware and software installation
• programming of components needed to provide basic call service
ISDN features are treated separately in the chapter devoted to ISDN feature
implementation.
This chapter builds on the ESN programming that is assumed to be already in
place. It is also built on the assumption that you have 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 mode of operation, uses analogue or digital TIE lines
as B-channels.
In shared mode, PRI hardware is required in addition to the existing TIE lines
interface cards.
