9. Install optional expansion boards; 6CO Board(s), 12EKT Board, 4SLT
Board(s), inside the KSU as required.
10. Install optional feature boards (4VAA or Voicemail Board ) inside KSU3 as
required.
11. Route 25‐pair, Unshielded Twisted Pair (UTP) telephone grade cable
through the appropriate KSU opening for EKT and CO line port interface
connections.
12. Route ancillary device cabling through the appropriate KSUL opening and
terminate as required (music source, printer/computer for Remote
Maintenance and Programming (RMP), Station Message Detailed
Recording (SMDR), external paging equipment, analog devices, door
phones etc.).
13. Using single‐pair Cross‐Connect (jumper wire); connect the various port
terminations of the KSU(s) from the Emerald ICE 66M1‐50 blocks to the
USOC termination point for CO lines to be connected to the system and
station cables for extensions to be connected to the system.
Whenever possible use of Bridging Clips are recommended for the
connection of CO Lines. This allows the individual Central Office (CO)
circuits to be disconnected for servicing while not affecting the other CO
resources of the system. We recommend ordering an RJ21-X for USOC
termination of CO Lines. This provides a convenient point of interface and
location for bridging clips.
Using Bridging Clips on station port wiring is not recommended since this
introduces a connection point that is not required. Service for any one
extension can be actuated via the jumper wire of that extension without
affecting any other station/extension ports/EKTs.
14. Install the terminal instruments (EKTs and DSSs) and any optional
terminal equipment, such as Door Phones or analog devices.
