line Type

1.3.6.1.4.1.351.110.4.3.1.1.1.1.4

This variable indicates the variety of DS1 Line implementing this circuit. The type of circuit affects the number of bits per second that the circuit can reasonably carry, as well as the interpretation of the usage and error statistics. The values, in sequence, describe: TITLE: SPECIFICATION: dsx1ESF Extended SuperFrame DS1 dsx1D4 AT&T D4 format DS1 dsx1E1 CCITT Recommendation G.704 (Table 4a) dsx1E1-CRC CCITT Recommendation G.704 (Table 4b) dsxE1-MF G.704 (Table 4a) with TS16 multiframing enabled dsx1E1-CRC-MF G.704 (Table 4b) with TS16 multiframing enabled dsx1E1clearchannel E1 clear channel, all DS0s can be used dsx1E1Q50 G.704 (table 14) In TS16 bits 5,7,8 will be set to 100 for all other cases bits 5,7,8 will have a value of 111. dsx1E1Q50CRC same as dsx1E1Q50 but with CRC. NOTE: All E1, E1-CRC, E1-MF or E1-CRC-MF are using DS0 on slot 1 for signaling and E1-MF or E1-CRC-MF use DS0 on slot 17 for synchronization. (Slot 1 and 16 is based on index 1 to 32 DS0) All DS0s can be used for any port when lineType is dsx1E1clearchannel. On a CESM card, only 'dsx1E1clearchannel' option is supported. When the lineType is dsx1E1Q50 the bits 5,7,8 of TS16 of frame zero will be forced to 100 else it will be 111. The default value for T1 is 'dsx1ESF' and for E1 is 'dsx1E1CCS'.
