DATASHEET

PM5349 S/UNI-QUAD

PMC-971239	ISSUE 6	SATURN USER NETWORK INTERFACE (155-QUAD)

When the received pointer returns to an in-range value, the

S/UNI/QUAD will interpret it correctly.

Note 10 - LOP will exit at the third frame of a three frame sequence consisting of one frame with NDF enabled followed by two frames with NDF disabled, if all three pointers have the same legal value.

The transitions indicated in the state diagram are defined in the following table.

Table 2: Pointer Interpreter Transition Description

Transition	Description

inc_ind/dec_ind	offset adjustment (increment or decrement indication)

3 x eq_new_point	three consecutive equal new_point indications

NDF_enable	single NDF_enable indication

3 x AIS_ind	three consecutive AIS indications

8 x inv_point	eight consecutive inv_point indications

8 x NDF_enable	eight consecutive NDF_enable indications

Note 1 - the transitions from NORM_state to NORM_state do not represent state changes but imply offset changes.

Note 2 - 3 x new_point takes precedence over other events and if the IINVCNT bit is set resets the inv_point count.

Note 3 - all three offset values received in 3 x eq_new_point must be identical.

Note 4 - "consecutive event counters" are reset to zero on a change of state except for consecutive NDF count.

The Pointer Interpreter detects loss of pointer (LOP) in the incoming STS-3c (STM-1) stream. LOP is declared on entry to the LOP_state as a result of eight consecutive invalid pointers or eight consecutive NDF enabled indications. The alarm condition is reported in the receive alarm port and is optionally returned to the source node by signaling the corresponding Transmit Path Overhead Processor in the local S/UNI-QUAD to insert a path RDI indication.

The Pointer Interpreter detects path AIS in the incoming STS-3c (STM-1) stream. PAIS is declared on entry to the AIS_state after three consecutive AIS indications. The alarm condition reported in the receive alarm port and is
