Register 032H: ICASM CAS Enable Indirect Access Data Register
CAS_EN
Bit
Bit 1-15
Bit 0
The CAS_EN bit is used to enable the insertion of CAS into the proper location in the
associated tributary. When CAS_EN is a logic one and the associated tributary is a T1, the
CAS bits and PP bits are inserted into the PPSSSSFR byte. When CAS_EN is a logic one
and the associated tributary is an E1, the CAS bits are inserted into TS#16 and proper data is
placed in the PP byte. When CAS_EN is a logic zero, both the CAS and PP bits are not
inserted.
When CAS insertion is enabled, the latency of the CAS bits through the SBSLITE is two
multiframes. For T1 tributaries, this is 48 frames or 6ms. For E1 tributaries, this is 32 frames
or 4 ms.
