Note
:
Address on the left side MUST BE identical to the address on the right side. There is
no interchange function for “pass-through” signals.
∗ Whenever 24-type or 29-type OLIUs are installed in main the range of STS-1s will be
from 1 to 12. Example: m-{1-12}.
† Ring cross-connection; 27-type OLIU in main.

Note
:
The STS1E circuit pack hardware switch must be set to “low-speed” to support
cross-connections. The “ring” parameter defines the ring carrying the continue signal. This
ring directly connects to the other drop and continue shelf.
∗ Whenever 24-type or 29-type OLIUs are installed in main the range of STS-1s will be
from 1 to 12. Example: m-{1-12}.
† Ring cross-connection; 27-type OLIU in main.
