Either telephone can be used to call the other line. In other words, the TLS-3A is a simple telephone network in a box. When a telephone connection is not available, or when installing a...
The green Power indicator alternates between full and half brightness when the TLS-3A is operating. If the Power indicator is dark, no power is connected to the TLS-3A. If it lights, but does not flicker, the TLS-3A’s internal processor is not working properly.
2. How to Install the TLS-3A Figure 2 Typical TLS-3A Installation The TLS-3A works with analog loop start telephone sets only. It will not work with ground start, proprietary, or digital phone sets. Follow these steps to install the TLS-3A: 1.
3. How to Operate the TLS-3A 40-400-00010, Rev. B The TLS-3A has one talk path between the two lines. When a telephone connected to either line goes off-hook while the other is still on-hook, the off-hook telephone receives dial tone. If the other telephone is already off-hook, the second telephone off-hook will not receive dial tone (silence).

A dialing error occurs when less than 7 digits are dialed or if the first digit is a 1 or 0 and less than 11 digits are dialed. The TLS-3A will issue a reorder tone (aka Fast Busy) approximately 8 seconds after the last DTMF digit is entered if a dialing error occurs.

Use one of the two- or three-digit telephone numbers assigned to the line you want to call, or use any seven-digit telephone number. Like the public telephone network, the TLS-3A will not accept a seven-digit number with a 1 or 0 as the first digit. Such a number produces a reorder tone.
