Function

SAPL

Input

B14 System Add Bus Payload Active (SAPL). The add

bus payload active signal indicates valid data within the

SBI bus structure. This signal must be high during all

octets making up a tributary. This signal goes high

during the V3 or H3 octet of a tributary to indicate

negative timing adjustments between the tributary rate

and the fixed SBI bus structure. This signal goes low

during the octet after the V3 or H3 octet of a tributary

to indicate positive timing adjustments between the

tributary rate and the fixed SBI bus structure.

In the flexible bandwidth configuration, SAPL may only

be asserted in response to a logic high on the

SAJUST_REQ. SAPL shall be high an equal or less

number of cycles than SAJUST_REQ. (Some

applications require an exact one-to-one

correspondence.)

The TEMAP-84 only monitors the add bus payload

active signal during the tributary timeslots assigned to

this device.

SAPL is sampled on the rising edge of SREFCLK.

SAV5

Input

C14 System Add Bus Payload Indicator (SAV5). The add

bus payload indicator locates the position of the

floating payloads for each tributary within the SBI bus

structure. Timing differences between the tributary

timing and the synchronous SBI bus are indicated by

adjustments of this payload indicator relative to the

fixed SBI bus structure.

All timing adjustments indicated by this signal must be

accompanied by appropriate adjustments in the SAPL

signal.

The TEMAP-84 only monitors the add bus payload

indicator signal during the tributary timeslots assigned

to this device.

SAV5 is sampled on the rising edge of SREFCLK.
