38.3.1 Channelized T3
In “channelized T3” configuration, T3 interfaces are carried inside the OC-3 (SONET)
optical links. Up to three T3 trunks can be channelized. To configure channelized T3
trunks, configure the Fiber Group as follows:

Fiber Group Interface Type
= OC3

Fiber Group Mapping Type
= STS1ofDS3
See Table 'PSTN Fiber Group Properties’ for details.
In contrast to the regular T3 coaxial interfaces, “channelized T3” configuration benefits
from the APS protection provided by the OC-3 (SONET) optical links.
In a “channelized T3” configuration, both the OC-3 PSTN Fiber Group Status Screen
(as shown in ‘Figure : OC-3 PSTN Fiber Group Status Screen) and the DS3 Status
Screen (as shown in ‘Figure DS-3 Status Screen) are accessible.
Configuration is also supported for both the PSTN Fiber Group and the T3 Interface,
as described in the previous sections.
