Function

SDV5

Output

Tristate

System Drop Bus Payload Indicator (SDV5). The

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 are

accompanied by appropriate adjustments in the SDPL

signal.

The TEMAP-84 only drives the payload Indicator signal

during the tributary timeslots assigned to this device.

SDV5 is updated on the rising edge of SREFCLK.

SBIACT

Output A3

SBI Output Active (SBIACT). The SBI Output Active

indicator is high whenever the TEMAP-84 is driving the

SBI drop bus signals. This signal is used by other

TEMAP-84s or other SBI devices to detect SBI

configuration problems by detecting other devices

driving the SBI bus during the same tributary as the

device listening to this signal.

This output is updated on the rising edge or SREFCLK.

SBIDET[0]

SBIDET[1]

Input

A15

B15

SBI Bus Activity Detection (SBIDET[1:0]). The SBI

bus activity detect input detects tributary collisions

between devices sharing the same SBI bus. Each SBI

device driving the bus also drives an SBI active signal

(SBIACT). This pair of activity detection inputs

monitors the active signals from two other SBI devices.

When unused this signal should be connected to

ground.

These inputs only have effect when the SBI bus is

configured for 19.44MHz (i.e. S77 is low).

A collision is detected when either of SBIDET[1:0]

signals are active concurrently with this device driving

SBIACT. When collisions occur the SBI drivers are

disabled and an interrupt is generated to signal the

collision.
