Circuit Emulation Service over Packet-Switched Network (CESoPSN) is supported on the Circuit Emulation MIC (MIC-3D-4COC3-1COC12-CE), for all values of N in NxDS0 interfaces. CESoPSN encapsulation is supported on NxDS0 interfaces.
An NxDS0 interface can be configured from either a channelized T1 interface (CT1) or a channelized E1 interface (CE1). The value of N is 24 when a DS0 interface is configured from a CT1 interface and 31 when a DS0 interface is configured from a CE1 interface.
