CHAPTER 3: Automatic Operation
3. Automatic Operation
The Phone Line Manager 208B prohibits incoming calls from direct access to any connected device. It will answer calls on
Line 1 and Line 2 on the first ring. Once the call is answered, it listens for the following transfer codes:
Line 1 Transfer Codes
Line 2 Transfer Codes
Port 1
(Automatic)
1100Hz CNG tone to route to Port 8
Port 2
Port 1
Port 3
Port 2
(Automatic)
Port 4
Port 3
Port 5
Port 4
Port 6
Port 5
Port 7
Port 6
Port 8
Port 7
Port 8
If the Phone Line Manager 208B detects any of these signals, it transfers the call to the desired port. If no signals are
detected, the call on Line 1 will be automatically transferred to Port 1 and the call on Line 2 will be automatically transferred
to Port 2.
The Phone Line Manager 208B will ring Ports 1 and 2 a maximum of 20 times each. If either port device does not answer
within 20 rings, the call will be disconnected.

4.1 Special operating notes
Before operating the Phone Line Manager 208B, be sure that you understand the following information concerning the
telephone equipment that is used with the Phone Line Manager 208B.
Fax CNG tones: Most faxes send audible beep tones called CNG (CalliNG) tones. This tone is a distinct beep that repeats
every three (3) seconds. Once a fax has dialed the destination fax number, it generates this tone while waiting for the
receiving fax to answer. Not all faxes transmit this tone when they place a call. Most, but not all faxes produce this tone
through their auto-dial feature, speed dial memory position, or by the operator pressing the fax machine’s start button after the
number is dialed. For best results, callers should have your fax number programmed into their fax machine’s “speed-dial”
memory.
