4 Switch Interface Administration

Digital Interfaces

Digital Interfaces

Digital interfaces are administered on a card-by-card basis; that is, digital parameters apply to individual digital circuit cards installed in the system.

The digital interfaces currently support the E1/T1 digital circuit card with the following protocols:

T1 A/B Robbed-bit E&M

E1 CAS

ISDN-Primary Rate Interface (PRI)

The process of administering the digital interfaces consists of selecting a protocol based on the circuit card type and either accepting the default values as displayed or changing the default values.

Accessing the Digital Interfaces Menu

The Digital Interfaces menu displays all digital protocols installed on your system. If there are no E/1T1 circuit cards installed in your platform, the Digital Interfaces selection does not appear in the Switch Interfaces menu.

Note: All selected options must match the corresponding options on the switch PBX or network to avoid service problems.
