Channel Bank
In configuration (b), voice traffic is delivered toward the network from a PBX through
individual FXS circuits. In this case, the FrameSaver NP 110 terminates the T1 facility
and provides a “drop” function that separates the DS1 into a voice bundle. The bundle
is then delivered to a channel bank for conversion into multiple FXS circuits and a sin-
gle V.35 frame relay User Interface data circuit for the router. This configuration fa-
cilitates inband access to the T1 performance through simple inband transport.
Behind Channel
Bank
In configuration (c), voice traffic is delivered toward the network from a PBX through
individual FXS circuits. In this case, a channel bank terminates the T1 facility and pro-
vides a “drop” function that separates the DS1 into multiple FXS circuits and a single
frame relay User Interface data circuit. These circuits can be delivered to a standard
FrameSaver NP 120 as V.35 or to a standard FrameSaver NP 110 as a DS1.
Second V.35
Drop Port
Figure 2-3 shows an application in which a third bundle of DS0s are integrated into the
T1 stream and delivered to a separate V.35 drop port. In this application, one group of
DS0s are assigned to the customers PBX via the DSX port and used for direct access
to the IXC’s inter-LATA dial network. The second group of DS0s are channeled via
our V.35 User (frame aware) port for use on the customer’s frame relay Virtual Private
Network. Then for security and bandwidth allocation purposes, the third group of
DS0s for Internet access are channelized to a different router via a V.35 Drop port.
Depending on the network architecture, the ISP could be co-located with the IXC DCS
or be remote from it, and the traffic on this bundle may or may not be frame relay.
This configuration could exist with configuration a, b, or c described on the previous
page.
