SPA-2CHT3-CE-ATM
From Cisco IOS XE Release 3.4S, ATM support for the SPA-2CHT3-CE-ATM is introduced. When configured
to operate in the ATM mode, CEoP SPAs support the ATM features.
The SPA-2CHT3-CE-ATM CEoP supports ATM operation only in the clear-channel mode. In this mode,
each SPA port provides a single high-speed ATM connection operating at the line rate of the port.
Guideline for Configuring ATM Connections on a SPA
Consider the following guideline before configuring the ATM connections on a SPA:
In the clear-channel mode, each port in the 2-Port Channelized T3/E3 ATM CEoP SPA provides a single
ATM connection operating at the T3line rate.
Configuring a Port on a CEoP SPA for ATM Operations
To configure a port on a CEoP SPA for ATM operations, you must:
1 Set the port to the ATM mode.
2 Configure an ATM permanent virtual circuit (PVC) for the port.
3 Configure a pseudowire for the ATM interface.
Configuring an ATM Interface
The router creates an ATM interface for each T3port that is configured for the ATM. The interface is in the
atm slot /subslot /port format, where slot /subslot identifies the SPA slot and subslot, and /port identifies the
port, for example, atm 2/1/0.
