193E framing, no integration, 1 multiframe freeze, replace robbed bit
signaling bits at SSER with ones.
NOTE:
1. During slip or alarm conditions, integration is limited to two multiframes to minimize signaling delay.
SLIP AND SIGNALING SUPERVISION LOGIC TIMING Figure 7
NOTES:
1. Integration feature disabled (SM0=SM1=0) in timing set shown.
2. Depending on present buffer depth, forcing ALN low may or may not cause a slip condition.
