19.52 Using Master Telephones
A master telephone (QMT-5302N(V)) is attached to a node and is configured to call other
specific master telephones.
Master telephones are called by pressing a switch on a telephone/page selector (QAZT-
5302DS or QAZT-5348DS).
In order to call one master telephone from another master telephone, you must correlate a
switch on one node to a switch on another node. See section 19.52.4 on page 206 for
instructions on how to do this.
The following 3 sections describe 3 applications of master telephones.
19.52.1 Calling Master-to-Master (Single Call)
In this two-node example, node 1 switch number 0 is correlated to node 2 switch number 0.
1. Press switch number 0 on node 1 to call node 2.
Node 1 and node 2 sound their buzzers and the green LEDs blink.
2. Press switch number 0 on node 2 to answer the call.
Node 1 and node 2 turn off their buzzers and green LEDs turn solid.
3. Press switch number 0 again on node 1 (or press switch number 0 on node 2) to
disconnect the call.
19.52.2 Calling Master-to-Master (Multiple Calls)
In a three-node system, an operator at node 1 can call both node 2 and node 3. In this
example the following correlations have been made:
•
Node 1 switch number 0 <--> Node 2 switch number 0
•
Node 1 switch number 1 <--> Node 3 switch number 0
•
Node 2 switch number 1 <--> Node 3 switch number 1
1. Press switch number 1 on node 1 to call node 3.
Node 1 and node 3 sound their buzzers and the green LEDs blink.
2. Press switch number 0 on Node 3 to answer the call from node 1.
Node 1 and node 3 turn off their buzzers and the green LEDs turn solid.
The operators at nodes 1 and 3 can talk to each other.
3. Press switch number 1 on node 2 to call node 3.
Node 2 and node 3 sound their buzzers and the green LEDs blink.
4. Press switch number 1 on node 3 to answer the call from node 2.
Node 2 and node 3 turn off their buzzers and the green LEDs turn solid.
The operators at all 3 nodes can now talk to each other.
5. Press switch number 0 on node 3 to disconnect the call from node 1.
6. Press switch number 1 on node 3 to disconnect the call from node 2.
