tributaryIdentifier—Specifier
for the tributary in the format pathChannel { ds1 | e1 } pathPayload/tributaryGroup/tributaryNumber
pathPayload—Payload number
for the path; value is 1 for SONET and in the range 1–3 for
SDH
tributaryGroup—Number, in
the range 1–7, that identifies the group within the path
tributaryNumber—Number of
the tributary within the tributary group; the value is in the range
1–4 if the tributary type is vt15 or tu11 and in the range 1–3
if the tributary type is tu12
