Add a Node to an In-Service 2-Fiber Ring Network
DO ITEMS BELOW IN ORDER LISTED . . . . . . . FOR DETAILS, GO TO
1. Overview: This procedure is used to add a "new node" to an existing and
in-service 2-fiber ring network. The "new node" is an add/drop-rings terminal
with/without an FT-2000 Lightwave Booster Amplifier (FT-LBA). The "new
node" must not be designated as the DS-NE. This procedure is written from
the "new node" perspective although action is required at two other nodes.
The "new node" will be connected between two operational nodes (called the
West node and East node). If adding a "new node" to an out-of-service
2-fiber ring network, refer to Acceptance: NTP-006 or to Acceptance:
NTP-011 (node operating with FT-LBA).
Required Test Equipment and Personnel:
Craft Interface Terminal (CIT)
Wrist Strap
Appropriate Optical LBOs
Technical assistance at two other nodes.
!
WARNING:
Unterminated optical connectors may emit invisible laser radiation. Eye
damage may occur if beam is viewed directly or with improper optical
instruments. Avoid direct exposure to beam.
!
CAUTION:
Use a static ground wrist strap whenever handling circuit packs or
working on an FT-2000 terminal to prevent electrostatic discharge
damage to sensitive components. See "Electrostatic Discharge (ESD)
Considerations" in Trouble Clearing: TAD-100.
NOTE:
Major alarms will be active at different times during this procedure.
