•
Circuit Type—Choose either
Local Orderwire
or
Express Orderwire
depending on the orderwire
path that you want to create. If regenerators are not used between ONS 15454 nodes, you can use
either local or express orderwire channels. If regenerators exist, use the express orderwire channel.
You can provision up to four ONS 15454 OC-N ports for each orderwire path.
•
PCM—Choose the Pulse Code Modulation voice coding and companding standard, either
Mu_Law
(North America, Japan) or
A_Law
(Europe). The provisioning procedures are the same for both
types of orderwire.
Caution
When provisioning orderwire for ONS 15454s residing in a ring, do not provision a complete orderwire
loop. For example, a four-node ring typically has east and west ports provisioned at all four nodes.
However, to prevent orderwire loops, provision two orderwire ports (east and west) at all but one of the
ring nodes.
