How The SR Cal1 Processor Works The SR Call Processor counts the number of bursts in the ring pattern of the telephone number called. It then directs the call to one of the numbered device ports at the rear of the unit. The device ports are output jacks that connect your phone devices (phones, MODEMs, FAX, answering and dictation machines) to the SR Call Processor. When you have attached the phone devices you wish to use, the SR Call Processor routes each different ring pattern (i.e.

2) Do I need barge-in protection?

If barge-in protection is not required (for example, in a voice-only application at home), certain phones may be attached directly to the telephone line. 3) Ease and expense of changing my telephone wiring.
V You will need to apply power to your SR with the supplied AC adaptor. Be sure to pick an installation location where a grounded 110VAC power outlet is nearby. You will also want to set the switch(es) on your SR for your particular application (See inside front cover). Initial Check Out Please check the box and make sure you have: -either an SR2 or SR3 Selective Ring Call Processor -a 12 VAC Class 2 power source -one silver modular line cord with RJ- 11 plugs on each end.
Single Line Installation A. Simple Plug-In (one jack, e x t e n s i o n s ) Ring Supervision: Barge-in Protection: Install, Ease/Expense Excellent Excellent Excellent To Telephone Co.
B. Wiring Modifications Ring Supervision: Barge-in Protection: Install, Ease/Expense Excellent Excellent Difficult V Materials Needed: 2 modular wall jacks, 1 line cord, station wire (perhaps). If possible, this is the best way to install your SR when you have extension telephones. Contact an installer if you need additional help. 1) Choose a suitable location for your SR. One good place to consider is near the point that the telephone line enters your home or building.
3) If you disconnect the incoming line from a jack, label the existing jack “TELEPHONES”. If you did not, install a jack, label it “TELEPHONES”, and connect the two wires going toward your phone equipment to the RED and GREEN terminals of this new jack. 4) Mount a modular jack* at the location of your SR and connect the telephone company incoming line to the RED and GREEN terminals. It may be necessary to run additional station wire* from the incoming line. Label this jack “LINE”.
C. Installation with Adapters: (only for use in homes where only one line is used, and each jack has four wires attached) Excellent Ring Supervision: Excellent Barge-in Protection: Install, Ease/Expense Good Materials Needed: 1 two-line splitter for each existing wall jack, 1 line cord. To Telephone Co. Central Office l= If your home has 4 or 6-wire cable to each wall jack, you can make your installation look electronically like installation B by using special 2-line (to 1-line) splitter adapters*.
4) Connect the “DEVICE 1” jack of your SR to the “LINE 2” side of the 2line adapter with a line cord. 5) Connect your data devices and/or other telephones to the DEVICE 2 (or 3) jacks on your SR. These devices or phones will be rung by your additional telephone number(s). 6) For each wall jack in your home, disconnect anything plugged into it. Insert a 2-line adapter and re-connect the cord to the ,“LINE 2” side of the adapter.
Partial Supervision (cont) To Telephone Co. Central Office In reality, this installation is fast, easy, and works great if you don’t need barge-in protection and if you don' t care if your other phones ring all the time. The best application is adding a FAX, MODEM, or answering machine on the second number. The obvious drawback is that even if you turn the barge-in switch “ON” on your SR, you can still interrupt a call with your extension phones.
E. Total Supervision with Multiple SR’s Ring Supervision Barge-in Protection: Install, Ease/Expense Excellent Nope! Excellent To Telephone Co. Central Office If total ring supervision is required for more than one phone, and barge-in protection is not needed, buying additional SR Call Processors may be less expensive than changing your wiring, especially if your site is wired in a user-unfriendly way, or if your extensions are in other buildings.
Multiple Line Installation A. Before a Key System Ring Supervision: Barge-in Protection: Install, Ease/Expense Excellent Excellent Good TO KEY PHONES You can only install your SR on the CO* side of the KSU. You cannot install it on the station or extension side. 1) Disconnect the desired line from the KSU. 2) Mount the SR in a convenient location near the KSU. Under two of the feet on the SR are mounting slots. 3) At the demarc, install an RJ-11 if one does not exist. Label it “LINE”.
4) If necessary, install an RJ-11 on the KSU side of this line. Connect the “DEVICE 1” jack to this RJ-11 with a line cord. 5) If necessary, run additional station wiring to the data devices and install modular jacks on each end. Connect the proper DEVICE jack on the SR to the close jack, and connect the data device to the far jack. B.
Commonly Asked Questions How does the SR Series Call Processor work? The SR Series Call Processor recognizes the ring pattern of incoming calls by counting the number of bursts in the pattern. Your original phone number has one long burst, your 2nd and 3rd numbers have 2 and 3 bursts, respectively. After counting the bursts, the call is routed to the phone device you have designated for answering that telephone number without ringing other phones in your home.
Why does my SR Call Processor repeatedly click-click when I pick up the line? If you cannot get a dial tone, and only hear a clickclick every two seconds or so, the SR does not have a good connection to the phone company. Check your installation and wiring for loose or open connections. Connect a single-line telephone directly to the incoming line. Check for dial tone and proper operation. A dead line should be reported to your telephone company.
