Description A CE1/PRI interface can work in either E1 mode (non-channelized mode) or CE1/PRI
mode (channelized mode).
A CE1/PRI interface in E1 mode equals a 2 Mbps interface without timeslot division.
Its logic features are the same like those of a synchronous serial interface. When
working in CE1/PRI mode, it is physically divided into 32 timeslots numbered from 0
to 31. Among them, timeslot 0 is used for transmitting the FSC information. This
interface can work as either a CE1 interface or a PRI interface.
After the CE1/PRI interface is enabled to work in E1 mode by using the using e1
command, the system automatically creates a serial interface numbered serial
interface-number:0, where interface-number is the number of the CE1/PRI
interface.
