Dial-Up Trunking - Nortel RLC Installation And Administration Manual

RLC description
PRI trunk
(56K channel mode)
T1/E1 trunk

Dial-up trunking

The RLC supports digital trunks for connections to the Remote Gateway 9100
Series units. The RLC shares the host PBX's digital trunks (ISDN PRI) for a
PSTN connection to the Remote Gateway 9100 Series unit.
QoS Transitioning Technology
The RLC supports PSTN interfaces for local calling when used in Voice over IP
(VoIP) mode. In this way, it also supports QoS Transitioning Technology.
For a further explanation of QoS transition functions, refer to "Adjustable QoS
using QoS Transitioning Technology" on page 19. For exact configuration
procedures, refer to "Configuring QoS" on page 211.
Bandwidth utilization
The voice compression algorithm that you choose when configuring DSP
resources determines the bandwidth utilization of the RLC. The RLC currently
supports the following compression algorithms with the Remote Gateway 9100
Series devices indicated in the table below:
