CES Cross-Connection on the Cisco 3660 Router
The Cisco 3660 router can deliver traditional PCM-encoded 64-kbps circuit-based voice over the ATM
OC-3 CES network module. To use this functionality, the multiservice interchange card (MIX) must be
installed on the Cisco 3660 router. T1/E voice channels on NM-xFE2W and NM-HDV network modules
can be transported across the MIX module to ATM OC-3 network modules (NM-1A-OC3XX-1V) over
an ATM network. PVC-based (permanent virtual circuit) CES allows service providers to quickly deliver
local or long distance voice, while SVC (switched virtual circuit) capabilities ensure that these services
are optimized for maximum profitability.
To install the MIX card, see the Installing the Multiservice Interchange Card in Cisco 3660 Routers
document. To configure CES, see the OC-3/STM-1 ATM Circuit Emulation Service Network Module
document.
Connecting ATM OC-3 Ports to the Network
To connect an ATM OC-3 network module to the network, insert a fiber-optic cable with one duplex SC
connector (see
Some network modules are shipped with a dust plug to protect this interface. Pull to remove it.
