M2000 Series Meridian Digital Telephones are designed to provide
cost-effective integrated voice and data communication. These telephones
communicate with the Meridian 1 using digital transmission ove r standard
twisted-pair wiring. They interface with the Meridian 1 using the Integrated
Services Digital Line Card (ISDLC), QPC578 or the Digital Line Card
(DLC), (NTAD02.). No additional hardware is required at the line circuit to
provide data communication.
M2000 Series Meridian Digital Telephones are connected to the system
through a two -wire l oop carryin g two i ndependent 64 kbs PC M channels with
associate d signaling channe ls. One of the two PCM channel s is dedicated to
voice while the other i s dedicat ed to data tra ffic. Li ne cords and h andset cords
on all M2000 Series Meri dian Digita l Telephones are equipped wit h standard
modular connectors for easy and quick connecting procedures.
The telephone interfaces with the Digital Line Card (DLC) or ISDLC in the

M2216ACD Headset interface
Using the Program key, you can adjust the headset/handset interface of the
M2216ACD-1 to optimiz e performance.
The M2216ACD-1 is compatibl e with most headset s. Amplified headse ts are
strongly recommen ded. Three settings are provided:
•Interface 1 (i.e. Plantronics type )
•Interface 2 (Liberatio n )
•Interface 3 (Handset)
Note: It is recommended that the headset user try usi ng their headset
with each of the three settings to determine wh ich works best for the m.
Trial with both internal and external calls is also recommended in each
setting to determine optimum performa nce .
Note: When the amplified headset is used, there are two choices of
volume control: the rocker control on the tel ephone and the sw itch on th e
headset. The sett ings which provi de for the clearest communicati on with
the least amoun t of di stort ion are when the ampli fie r has a high er se tti ng
than the telephone volume control.
The supervisor and agent jacks are not interchangeable. A headset must be
plugged into the agent jack if the telephone is to receive ACD cal ls.
Note: Any recording device con nected to the receive path of an M2000
Series Meridian Digital Telephon e must meet these requirements:
•isolate power source from the headset /handset jack
•connect in parallel across pins 3 and 4 of the handset/headset jack
•load impedance at le as t 8K ohms across the audio band

Message Wait ing lamp ke y Each M2000 Seri es Meridian Di gital Tele phone
has a red tria ngle in the upper ri ght-hand corner that li ghts bright ly to in dicate
a message i s wai ting. This LED is t he prim ary m essage wa it ing indica tor an d
lets you kno w a message is wa iting re gardle ss of whethe r the te lephon e ha s a
message waiting key/lamp pair. You must have Message Waiting allowed
Class of Service. See LD 11, X11 Admi nist rati on (553-3001-311).
If you do assign a message waiting key/lamp pair, there will be two
indications of a message waiting :
•the red Message Waiting triangle lights
•the LCD associated with the Message Waiting key flashes
You may assign an Autodial key that dia ls the message center (or voice mail
system) to avoid the double indication or have no key/lamp pair assigned to
the mess a g e center.
The Message Waitin g lamp is also used to indicate security of the M2016S.
The red LED triangle light s steadily when the phone is not secure . (The phone
is not secure when the handset is off the hook, when the phone is ringing, or
whenever the handset/piezo relays are connected.) The red LED triangle
blinks when a me ssage is waiting.
Handsfree/Mute key ( M2008HF & M2616 only) Handsfree is software
assignable on the M2008HF/ M2616. This all ows you to t alk to a nothe r party
without lifting the handset. Activate Handsfree by depressing the
Handsfree/Mute key (key 15, top left for M2616; key 6, below Program for
M2008HF) or by sele cting a DN wit hout lif tin g the hands et. Onc e Handsfre e
is activ ated, it can be deactivated by pi cking up the ha ndset or by ending the
call using the Relea se (Rls) key. If Handsfree is not software ass igned, you
can assign any other feature to the “Handsfree” key.
Note: Software Control - CLS Class of Service for M2008HF
The Class of Service fe ature cons istent wi th M2616 Handsfre e control allows
system administrators to enable/disable the Handsfree option on the
M2008HF (Handsfree) telephone via software. M2008HF telephones ship
from the factory with a hardware jumper enabled to allow the Handsfree
option for existing software releases.
Meridian 1 Telepho nes Description and Specifications

Release 21.4 1 and later software will now override the har dware setting and
default to Handsfree denied (HFD.) If the handsfree option is des ired, the
system administrator simply enables Handsfree via a Class of Service prompt
(HFA) included on Overlay 11 programming for the M2008 telephones
(consistent with M2616).

example, when the telephone is idle, press ing the Handsfree/Mute key turns
on the integrated Handsfree and s elects a DN (depending on line selection as
assigned through COS), a llowing the user to make a call. When a ca ll comes
in to an M2008HF/M2616 and the set is ringing, pressing the Handsfree/Mute
key turns on the Handsfree and allows the user to answer the incoming
(ringing) call (depending on COS-assign ed line select ion) witho ut picking up
the handset.

M2000 Series Meridian Digital Telephone relocation
This section describes how to reloc ate an M2000 Series Meridian Digital
Telephone and its associated dataport Terminal Number (TN) without the
intervention of a craftsperson.
Modular Tel ephone Re locat ion is d esign ed s pecifi call y for th e M2 000 Serie s
Meridian Digital Telephones and is an enhancement to Automatic Set
Reloca tion. If dataport TN inform ation exists for the terminal, it is
automatically relocated when the telephone is relocated.
When a telephone is relocated-out, a relocation block is built to store the
relocation information in the protected data area. The relocation block
includes the old TN, the terminal ID information, the serial number of the
telephone, and other information.
This feature uses the unique serial numbe r and te rmi nal ID of the M2000
