Interfaces formed by CE1/PRI and CT1/PRI interfaces (except ISDN PRI interfaces). The interface name is Serial and the interface logic is the same as that of synchronous serial interfaces.
Interfaces formed by CE3 interfaces. The interface name is Serial and the interface logic is the same as that of synchronous serial interface.
Interfaces formed by E1-F and T1-F interfaces. The interface name is Serial and the interface logic is the same as that of synchronous serial interfaces.
Interfaces formed by E1/T1 interfaces that are channelized from CPOS interfaces. The interface name is Serial and the interface logic is the same as that of synchronous serial interfaces.
POS interfaces.
