No. Ala Q.703 it sends LS PR when it recovers and only then both sides exchange LSR. Neither side resynchronizes until the link becomes unblocks which requires no processor outage (local or remote). > 2. again, both sides are in PO and both sides recover - each side sends LS > PR. Should both sides exchange just one pair of LS Ready (stream 1) messages > or should they perform resynchronization sequence independently? Each side resynchronizes independently per Q.703. The sequence when the last terminal recovers is the same as though only one processor was out. --brian -- Brian F. G. Bidulock [email protected] http://www.openss7.org/
