the SBI bus. The V5 and R octets do not carry any information and are fixed to a
zero value. The V3 octet carries a T1 data octet but only during rate adjustments
as indicated by the V5 indicator signals, DV5 and AV5, and payload signals,
SDPL and SAPL. The PPSSSSFR octets carry channel associated signaling
(CAS) bits and the T1 framing overhead. The DS0 octets are the 24 DS0
channels making up the T1 link.
The V1,V2,V3 and V4 octets are fixed to the locations shown. All the other
octets, shown shaded for T1#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 T1 is identified via the V5 Indicator signals, SDV5 and
SAV5, which locate the V5 octet. When the T1 tributary rate is faster than the
SBI nominal T1 tributary rate, the T1 tributary is shifted ahead by one octet which
is compensated by sending an extra octet in the V3 location. When the T1
tributary rate is slower than the nominal SBI tributary rate the T1 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.
