DS3 information bits. Table 33 shows the DS3 multi-frame format that is packed

into the grey region of Table 31. In this table V5 indicates the V5 octet which is

also a stuff octet, R indicates a stuff octet and B indicates the 11 octet DS3

block. Each row in Table 33 is a DS3 multi-frame. The DS3 multi-frame stuffing

format is identical for 5 multi-frames and then an extra stuff octet after the V5

octet is added every sixth frame.

DS3 asynchronous timing is compensated via the H3 octet. DS3 link rate

adjustments are optionally passed across the SBI via the Linkrate octet. DS3

alarm conditions are optionally passed across the SBI bus via the Linkrate octet.

E3 Tributary Mapping

Table 34 shows a E3 tributary mapped within the first synchronous payload

envelope SPE1. The V5 indicator pulse identifies the V5 octet. The E3 framing

format does not follow an 8KHz frame period so the floating frame located by the

V5 indicator and shown in grey in Table 34, will jump around relative to the H1

frame on every pass. In fact the V5 indicator will be asserted two or three times

per H1 frame, as is shown by the second and third V5 octet in Table 34. The V5

indicator and payload signals indicate negative and positive rate adjustments

which are carried out by either putting a data byte in the H3 octet or leaving

empty the octet after the H3 octet.
