After you configure the E1 channels, configure SAToP options on them in the same
way as for E1 interfaces. See "Setting the SAToP Options" on page 536.
Configuring SAToP Emulation on T1/E1 Interfaces on Circuit Emulation PICs
This configuration example applies to the mobile backhaul application shown in
Figure 49 on page 530.

Circuit emulation PICs with SONET and SDH ports require prior channelization down
to T1 or E1 before configuring. Only T1/E1 channels support SAToP encapsulation
or SAToP options.

Emulation PICs configured for SAToP do not result in alarm indication signal (AIS)
defect. As a result, the T1/E1 interfaces remain up.
