My understanding is that there are two orderwire circuits on any (vendor
supported) SONET transmission system, E1 and E2. E1 allows for SOH
orderwire between SONET sections (Regen sites/Huts), E2 allows for LOH
orderwire between SONET line terminating equipment (adm).
I don't see any way to utilize the 64k in J1 (Path Trace), as J1 contains
a repeated fixed-length string.
Is there any equipment which provides for a path layer orderwire in the
SPE?
