Prerequisites for Installation
The following items are required before installing the EXTender.
Network Requirements
•
The MCK T1/PRI card provides network termination. If you choose not to use the MCK T1/PRI card, you
must make sure the appropriate network terminating devices are installed, configured, and functioning
at both the corporate facility and the branch office. These network devices must support one of the fol-
lowing:
•
an RS-232, V.35, or RS-530 synchronous serial interface
•
a Voice over IP (10/100BaseT) interface
•
Connect the Remote unit to the phones using proper wiring with adequate punch down blocks. Use "Pin
Assignments (25-Pair Cable) on page' 19 as a guide, and provide the RJ-21 female connector.
•
Branch Office T1 / PRI Provisioning for Local Dialing
•
DTMF signaling (can be pulse)
•
*Wink (received) immediate (transmit out) start
•
B8ZS coding
•
ESF framing
•
You can use the default DS0 DN or select them individually and indicate how the line will perform
(i.e Incoming/Outgoing).
*Wink / Immediate essentially means that for outbound calls our CSU/DSU needs Wink Start and for
inbound calls Immediate Start. For outbound Wink start, our CSU/DSU will seize the line and wait for
the network to send a wink. After receiving the Wink the CSU/DSU will then start pulsing out the dig-
its. For inbound calls, the network should just seize the line. The CSU/DSU does not accept inbound
digits and will not produce a wink.
•
If using a PRI ensure that the circuit has been provisioned by the Telcos to include NO NFAS and if
needed DID provided. This way we can assign inbound calls on the local PRI to specific phones on the
EXTender 7000.
Space Requirements
•
The distance from the phones to the EXTender should NOT exceed 500 feet.
