Provisioning overview 1-

This chapter identifies the traffic-related provisioning required to set up a newOC-3 linear system or unidirectional path switched ring (UPSR).

Traffic-related provisioning of an OC-3 system should take place only after thenetwork elements have been commissioned and tested (

Shelf Setup Guide

). Inaddition, all user and administration accounts for the system should be

provisioned (

GUI

Security and Administration

, 323-1051-302G), and TBOSfacilities (

GUI Network Surveillance

, 323-1051-520G) should be provisionedbefore traffic-related provisioning commences.

Traffic-related provisioning for a new system consists of setting up systemsynchronization and adding new DS1, DS3, or EC-1 services. Alltraffic-related provisioning can be performed from one network element.

For synchronization procedures, see GUI Provisioning Synchronization

,323-1051-310G. For procedures on provisioning DS1 and EC-1 services, seeGUI Provisioning DS1 Services

, 323-1051-320G, and GUI Provisioning EC-1Services

Step Action

1 From the available NE(s) list in Network View, select the network element you

wish to log in to.

2 Click Login to open the Login to NE dialog box.

Procedure 2-2Adding or deleting DS3 equipment and facilities

Use this procedure to add or delete DS3 equipment and facilities in an OC-3network.

This procedure describes how to provision or delete the DS3 mapper andfacility for the near-end and far-end network elements of an end-to-end DS3service. To provision or delete crossconnects, see chapter 3 for linear systemsand chapter 4 for UPSRs.

If you are provisioning a DS3 mapper and facility for an empty equipment slot,make sure the last equipment that occupied the slot and its related facilities andcrossconnects have been deleted.

If you are deleting DS3 equipment or facilities, you must delete thepassthrough network element crossconnects and the DS3 crossconnects, thenthe facility, then the equipment, if required.

Make sure the end-to-end DS3 service is not carrying traffic before you deleteit. Deleting a DS3 service that is carrying traffic causes traffic loss.

Action

Step Action

Adding DS3 equipment

1 In the Shelf view, determine whether the slot contains a deleted circuit packor is empty. (A deleted circuit pack appears without a label. An empty slot

appears with no circuit pack.)

2 Determine which procedure you require:

Procedure 3-1Provisioning unidirectional drop and continue for aDS3 service

Use this procedure to provision unidirectional drop and continue for a newDS-3 service in a linear system.

This procedure describes how to add or delete unidirectional drop and continuefor the near-end, passthrough, and far-end network elements of a DS-3 service.

Make sure the DS-3 service is not carrying traffic before you delete it. Deletinga DS-3 service that is carrying traffic causes traffic loss.

If you are provisioning a 1+1 protected connection, ensure an FFP isprovisioned for the optical interfaces. Then, when you provision the STS-1 or

VT1.5connection on the working optical interface, the connection isautomatically set up on the mate optical interface as well.

The order of the FromAID and the ToAID is important for a unidirectionalconnection. The FromAID identifies the circuit pack from which the signaloriginates. The ToAID identifies the circuit pack to which the signal is going.

RequirementsTo perform this procedure, you must

ensure the equipment and facilities that will be used by the plannedcrossconnects are provisioned and in service

ensure 1+1 protection has been provisioned for the OC-3 facilities, if youare provisioning a 1+1 protected connection. If you need to provisionprotection for the OC-3 facilities, see the procedure in GUI ProvisioningOC-3 Equipment and Facilities, 323-1051-350G.

obtain or create an DS-3 traffic map for the linear system requiringcrossconnect provisioning

ensure the correct shelf processor is installed in the shelf. If the shelf is anOC-3 Express shelf and you are provisioning add-drop or passthroughconnections, you must install an SPe on all add-drop multiplexer (ADM)nodes and passthrough nodes.

Procedure 3-2Provisioning bidirectional crossconnects for a DS3service

Use this procedure to provision bidirectional crossconnects for a new DS3service in a linear system.

This procedure describes how to add or delete the DS3 crossconnects for thenear-end, passthrough and far-end network elements of a DS3 service.

Make sure the DS3 service is not carrying traffic before you delete it. Deletinga DS3 service that is carrying traffic causes traffic loss.

If you are provisioning a 1+1 protected connection, ensure an FFP isprovisioned for the optical interface circuit packs. Then, when you provision

the DS3 connection on the working optical interface circuit pack, theconnection is automatically set up on the mate optical circuit pack as well.

Procedure 3-3Provisioning unidirectional crossconnects for a DS3service

Use this procedure to provision unidirectional crossconnects for a new DS3service in a linear system.



If you are provisioning a 1+1 protected connection, ensure an FFP isprovisioned for the optical interface circuit packs. Then, when you provision

the DS3 connection on the working optical interface circuit pack, theconnection is automatically set up on the mate optical circuit pack as well.



ensure 1+1 protection has been provisioned for the OC-3 facilities, if youare provisioning a 1+1 protected connection. If you need to provisionprotection for the OC-3 facilities, see the procedure in GUIProvisioningOC-3 Equipment and Facilities, 323-1051-350G.

obtain or create a DS3 traffic map for the linear system requiringcrossconnects provisioning.

ensure the correct shelf processor is installed in the shelf. If you areprovisioning passthrough or add-drop multiplexer (ADM) connections, allADM nodes and passthrough nodes must have an SPe installed.
