RE: (ASCEND) Quiescenting PRIs
The US does not follow the ITU standards, generally
the ITU comes up with a flavor, then Bellcore/ANSI
releases theres.
For a channel to remain blocked, the host providing the
channel must provide the BLO every 4-5 minutes. Lack of
this message with a good Level 2 on the circuit with D
Channel operational, an UBL will be sent to the receiving
CPE, which the TNT responds to with a BLA, thereby
releasing the channel from blocking.
Simple fix would be to put a state on that circuit as being
blocked, and not respond with BLA, but with a RESET OUT OF
SERVICE message.
just my 2 cents.
