5.
This data sheet assumes a particular nomenclature of the T1 and E1 operating environment. In each 125μs T1
frame, there are 24 8-bit channels plus a framing bit. It is assumed that the framing bit is sent first followed by
channel 1. For T1 and E1, each channel is made up of 8 bits, which are numbered 1 to 8. Bit 1, the MSB, is
transmitted first. Bit 8, the LSB, is transmitted last.
Locked refers to two clock signals that are phase- or frequency-locked or derived from a common clock (i.e., a
1.544MHz clock can be locked to a 2.048MHz clock if they share the same 8kHz component).
