Framer Register Architecture
NT1 Errored Event Enable Register
These bits enable the errored events used to determine errored and severely errored seconds at the network termi-
nation-1 interface. NTSa6-C, NTSa6-8, NTSLIP , NTAIS, NTLMFA, and NTLFA are the Sa6-C, Sa6-8, SLIP , AIS,
LMFA, and LFA errored events, respectively, as referred to the NT1 interface. A 1 in the bit position enables the cor-
responding errored event. The default value of this register is 00 (hex).
Table 124. NT1 Errored Event Enable Register (FRM_PR16) (Y70)
NT1 Remote End Errored Event Enable Register
These bits enable the errored events used to determine errored and severely errored seconds at the network termi-
nation-1 remote end interface. NTRERFA, NTRESLIP , NTREAIS, NTRELMFA, NTRELFA, NTRESa6-C, NTRESa6-
F, NTRESa6-E, and NTRESa6-8 are the RFA, SLIP, AIS, LMFA, LFA, Sa6-C, Sa6-F, Sa6-E, and Sa6-8 errored
events, respectively, as referred to the NT-1 remote end interface. The default value of this register is 00 (hex).
Table 125. NT1 Remote End Errored Event Enable Registers (FRM_PR17—FRM_PR18) (Y71—Y72)
Automatic AIS to the System and Automatic Loopback Enable Register
The default value of this register is 00 (hex).
Table 126. Automatic AIS to the System and Automatic Loopback Enable Register (FRM_PR19) (Y73)
* One occurrence of any one of these events causes an errored second count increment and a severely errored second count increment.

Automatic System AIS. A 1 transmits AIS to the system whenever the receive framer is
in the loss of receive frame alignment (RLFA) state.
Automatic System AIS CEPT CRC-4 Timer Expiration. A 1 transmits AIS to the sys-
tem after the CRC-4 100 ms or 400 ms timer expires. AIS is transmitted for the duration
of the loss of CRC-4 multiframe alignment state.
Reserved. Set to 0.
Transmit System AIS. A 1 transmits AIS to the system.
Automatic Line Loopback Enable. A 1 enables the framer section to execute the DS1
line loopback on or off commands without system intervention.
Reserved. Set to 0.
Automatic FDL Line Loopback Enable. A 1 enables the framer section to execute a
line ESF FDL loopback on or off command without system intervention.
Automatic FDL Payload Loopback Enable. A 1 enables the framer section to execute
a payload ESF FDL loopback on or off command without system intervention.
