16 Port Analog Line Circuit Pack
The TN2215/TN2183 provides 16 analog port interfaces. Each port supports 1 telephone, such as 500 (rotary dial) and 2500 terminals (DTMF dial) from a tip/ring pair. Each port also sends or receives signaling to and from a station; such as an analog telephone, answering machine, facsimile and loop-start CO port AUDIX. The TN2215/TN2183 provides rotary digit 1 recall, ground-key recall, and programmable flash timing. Additional support is provided for selectable ringing cadence, LED message waiting, and secondary lightning protection.
The TN2215/TN2183 supports on-premises (in-building) wiring with either touch-tone or rotary dialing and with or without the LED message waiting indicators. It supports off-premises wiring (out-of-building only with certified protection equipment) with either DTMF or rotary dialing, but LED message waiting indicators are not supported off-premises. Neon message waiting indicators are not supported.
