HIGH DENSITY 84/63 CHANNEL VT/TU MAPPER
AND M13 MULTIPLEXER
indicated by the V5 indicator signals, SDV5 and SAV5, and payload signals,
SDPL and SAPL. The PP octets carry channel associated signaling phase
information and E1 multiframe alignment. TS#0 through TS#31 make up the E1
channel.
The V1,V2,V3 and V4 octets are fixed to the locations shown. All the other
octets, shown shaded for E1#1,1, float within the allocated columns maintaining
the same order and moving a maximum of one octet per 2KHz multi-frame. The
position of the floating E1 is identified via the V5 Indicator signals, SDV5 and
SAV5, which locate the V5 octet. When the E1 tributary rate is faster than the E1
tributary nominal rate, the E1 tributary is shifted ahead by one octet which is
compensated by sending an extra octet in the V3 location. When the E1
tributary rate is slower than the nominal rate the E1 tributary is shifted by one
octet which is compensated by inserting a stuff octet in the octet immediately
following the V3 octet and delaying the octet that was originally in that position.
When the SYNCH_TRIB bit is set for a tributary, the timeslot alignment is
precisely as presented in Table 29.
