5-14 INSTALLING TELEVANTAGE
Maximum cabling distances
The maximum cabling distance between an analog phone and an HDSI/x analog station board
is one mile (5280 feet.) The maximum cabling distance between an analog phone and a DISIx
analog station board or DI0408LSAR2 integrated trunk and station board is 3500 feet. The
maximum cabling distance between a Toshiba digital phone and the Toshiba Strata CS-DKTU
station board is 1000 feet.
SIP phone, H.323 phone, and IP gateway wiring requirements
IP phones and IP gateways are connected to your network via an Ethernet connection. Your
TeleVantage Server must also be connected to your network via Ethernet. For devices connected
to an IP gateway, see the wiring requirements in the documentation provided by the IP gateway
manufacturer.
Replacing an existing PBX
If you are replacing an existing PBX with TeleVantage, the information in this section may
apply to you.
Wiring punch down blocks to TeleVantage
Punch down blocks are commonly used to terminate 50-pair cables from offices to the wiring
closet at the company location, and from the wiring closet to the telephone company. Each
phone connection from this punch down block—that is, each station or trunk—must be
connected to a wire terminated with an RJ-11 connector in order to be connected to the Dialogic
station breakout box or trunk board.
Wiring patch panels to TeleVantage
If your offices are wired to patch panels, you can use a standard phone cord with RJ-11
connectors from the patch panel to the Dialogic station breakout box. This method assumes that
the patch panel accepts RJ-11 connectors. Network patch panels generally use RJ-45 connectors
but often accept RJ-11 connectors as well.
Replacing telephones connected directly to trunk lines
If you are not replacing a PBX and your office phones are connected directly to trunk lines, the
office may need to be rewired. Trunk lines must come to a central location at the TeleVantage
Server and station lines must be wired from the TeleVantage Server to the offices.
