CHAPTER 4: Operation 4. Operation This chapter contains special operating notes that you should read before operating the Line Share 120H. The sections following the operating notes provides instructions for answering and routing your incoming calls. 4.1 Fax CNG Tones Before operating the Line Share 120H, make sure that you understand the following information about fax equipment that is used with the Line Share 120H. Fax CNG tones: Most faxes send audible beep tones called CNG (CalliNG) tones.
LINE SHARE 120H 4.2 Standard Operations When a call comes in, all the phones begin to ring (including extension phones, phones connected to the PHONE and TAD ports). The Line Share 120H allows 6 rings to the telephones before it automatically transfers the call to the FAX/MODEM port.
CHAPTER 4: Operation 4.3 Answering Incoming Calls You can answer incoming calls from an extension phone or from a phone device connected to the TAD or PHONE port. You can then conduct the call normally, for as long as you like. 1. If, after answering a call, you hear silence on the line, the call is likely coming from a fax that does not produce a CNG signal.
LINE SHARE 120H *To assist the Line Share 120H in automatically transferring calls that produce a CNG tone, you should leave a four-second silent period at the beginning or end of your answering machine announcement message. To accommodate auto-dial faxes that do not produce CNG tones, the Line Share 120H monitors the line 20 seconds after a call is answered on the TAD port.
CHAPTER 4: Operation 4.6 Placing an Outbound Call You can place an outbound call from the PHONE port, unless another port is in use. If another port is in use, you will hear silence when you attempt to place a call. If the line is clear when the calling device goes off-hook, you receive a dial tone and can place the call normally. During an outbound call, you can also receive a transmission from someone that is ready to transmit.
LINE SHARE 120H NOTE Not all modem comma (,) commands delay dialing for a 2-second interval. See your modem user’s manual and adjust the number of commas you use accordingly. When you or your answering machine answers, the Line Share 120H detects the tones and routes the call to the FAX/MODEM port.
CHAPTER 5: Troubleshooting 5. Troubleshooting/Helpful Hints • Why are fax calls being routed to my telephone and/or answering machine? • The Line Share 120H is a semi-automatic line sharing device, therefore calls are routed first to the TAD and PHONE ports. When a device connected to one of these ports answers a call, the Line Share 120H then listens for fax tones to transfer the call. If you answer a call and hear a fax tone, keep the phone off-hook until your fax answers and then hang up.
