NOTE:
This procedure treats the DRI EC-1 configuration as
separate components which use the cross-connections to
integrate the components into the DRI configuration. The
EC-1 Dual Ring Interworking (DRI) configuration is
established by first equipping the proper nodes with the
EC-1 interfaces and then establishing DS1/DS3 service
through the network. The procedures for establishing service
reference the proper cross-connection procedure (DLP-550)
for making the necessary cross-connections.
NTP-034Establish Initial Low Speed EC-1 Interface
NTP-0042. Establish Initial End-to-End DS1 Service, if required.
NTP-0053. Establish Initial End-to-End DS3 Service, if required.
