System Configuration

System Approach

V5.2 type subscriber line signaling

compatible with existing infrastructure

PSTN-based services available

R2/No.7 type intersystem signaling

independent network configuration and services available

V5.2

Supports concentration of Subscribers All subscribers “share” the trunked E1 Interface

Allow up to 16 2-Mbps links to be grouped Controlled by a single interface control channel
