Introduction
This chapter provides feature, add-on module, relocation, and specification
information for the M2006, M2008, M2008HF, M2616, and M2216ACD
Meridian Modular Telephones.
The Meridian Modular Telephones are designed to provide cost-effective
integrated voice and data communication capability. They interface with the
Digital Line Card (DLC). No additional hardware is required at the line
circuit to provide data communication.
Meridian Modular Telephones are connected to the system through a
two-wire loop carrying two independent 64 Kb/s PCM Channels with
associated signaling channels. One of the two PCM channels is dedicated to
voice while the other is dedicated to data traffic. Line cords and handset cords
on all Meridian Modular Telephones are equipped with snap-in TELADAPT
connectors for easy and quick connecting procedures.
Three distinct versions of Meridian Modular telephones, distinguished by the
first four letters in the upper left-hand corner of the model identification label
on the bottom of the telephone, are available. The three versions are the
“NTZK” models, the “NT2K” models with date code prior to April 24, 1998,
and both the “NT9K” models and the “NT2K” models with date code of April
24, 1998 and later. The two jacks face in the same direction on “NT2K” and
“NT9K” telephones, and in opposite directions on “NTZK” telephones.
When appropriate, differences between the models are noted in this
document.
