Description
The CS61318 is an E1 primary rate line interface unit.
This device combines the complete analog transmit and
receive circuitry for a single, full-duplex interface E1
rates. The device provides jitter attenuation compliant to
CTR12/TBR13 without requiring an external crystal. Al-
so, the CS61318 is pin and function compatible with the
Level One LXT318.
In addition to a basic hardware control mode, a host
mode is available that gives the user an enhanced func-
tionality via a serial microprocessor interface. The
extended features include custom pulse shape genera-
tion, AIS and LOS monitoring functions, signal strength
monitoring, and generation and detection of loop up and
loop down codes.
