Reader’s Note

This data sheet assumes a particular nomenclature of the E1 operating environment. There are 32 8-bit

timeslots in E1 systems which are numbered 0 to 31. Timeslot 0 is transmitted first and received first.

These 32 timeslots are also referred to as channels with a numbering scheme of 1 to 32. Timeslot 0 is

identical to channel 1, timeslot 1 is identical to channel 2, and so on. Each timeslot (or channel) is made

up of 8 bits which are numbered 1 to 8. Bit number 1 is the MSB and is transmitted first. Bit number 8 is

the LSB and is transmitted last. Throughout this data sheet, the following abbreviations will be used:

FAS

Frame Alignment Signal

CAS

Channel Associated Signaling

Multiframe

International Bits

CRC4

Cyclical Redundancy Check

CCS

Common Channel Signaling

Additional bits

E-bit

CRC4 Error bits
