Cross-Connection Provisioning Commands 8
Cross-connections can be entered and deleted using the following commands:
■ ent-crs-sts1 (Enter Cross-Connection STS-1) — This command
creates STS-1 signal cross-connections.
■ dlt-crs-sts1 (Delete Cross-Connection STS-1) — This command
deletes STS-1 signal cross-connections.
■ ent-crs-vt1 (Enter Cross-Connection VT1.5) — This command creates
VT1.5 signal cross-connections.
■ dlt-crs-vt1 (Delete Cross-Connection VT1.5) — This command
deletes VT1.5 signal cross-connections.
■ ent-crs-sts3c (Enter Cross-Connection STS-3c) — This command
creates STS-3c signal cross-connections.
■ dlt-crs-sts3c (Delete Cross-Connection STS-3c) — This command
deletes STS-3c signal cross-connections.
■ cnvt-crs (Convert Cross-Connection)—This command converts an
existing STS-1 cross-connection to 28 individual VT1.5 cross-connections
with the same endpoints as the STS-1 cross-connection. VT1.5 signals
carried within the original STS-1 appear in the same time slots in the
upstream or downstream DDM-2000 OC-3 before and after the conversion
takes place.
The cnvt-crs command has the unique ability to convert an existing STS-1
signal into its component 28 VT1.5 signals. This conversion enables an easy
upgrade of existing STS-1 drop networks to DS1 add/drop networks. No inverse
capability is available to convert 28 VT1.5 signals back to a single STS-1 cross-
connection.
DDM-2000 OC-3 systems provide flexible routing of STS-1 and VT1.5 signals
between high-speed and function unit interfaces for ring applications. These
cross-connections are entered using the CIT and are shown in Table 8-8 through
Table 8-19.
