Overview
Digital trunks are now supported in both Main Option 11C cabinets and IP
Expansion cabinets. This increased capability is possible with the
introduction of IP daughterboards in expansion cabinets and 100baseT or F
connectivity with the Main cabinet.
This chapter provides the information required to install PRI on a Meridian 1
Option 11C system:
• hardware and software installation
• programming procedures for basic call service.
While either the hardware or software may be installed first, the PRI cannot
be enabled and tested until both are completed.
