SSMB Code to Quality Level Assignment

Quality levels between 1 and 16 may be configured against each SSMB code. One (1)
is the highest quality level. Only the codes assigned by the operator may be used
when performing the configuration described in Sections 6.9, 6.11.1.
Note:

SASE Mode

The equipment can be configured in Stand Alone Synchronisation Equipment mode
(SASE) or one of the Enhanced SASE Modes (ESM). An external SASE regenerator
is used to clean the timing signal on the T4 output before it is fed back into the T3
input.
