TELEPHONE INTERFACE
INTRODUCTION
The Telephone Interface allows you to use home phones to receive and answer calls from
the automatic entry system and you can also forward them externally via a telephone line.
Therefor the (internal) home phone can receive calls from the street panel and from an
external line (telephone line). The latter always has the priority over the street panel in case
of receiving calls simultaneously and before having answered it.
The key feature of this Telephone Interface is that a single reference works for analogic 4+N
and VDS installations.
Other new features include:
Audio level settings from the phone.
The chance of changing the conversation mode to half-duplex or simplex mode dy-
namically.
Remote access from an external line (protected by a PIN code), to all functions avail-
able to internal telephones: activation of the relay, programming, connection to the
street panel, door open....etc.
Call forward. If there is no response from the internal telephones, it is forwarded to a
second telephone when the fi rst one does not answer.
Confi gurable time parameters.
Compatible with advanced telephone services (the use of * and #).
The use of pause in the external call number.
External signal of forward mode (open collector output).
Notice: The maximum number of telephones connected to the telephone interface that gua-
rantees the proper operation is 4 (just like with the telephone companies).
The interface accepts different confi gurations and working modes. These are the available
modes:
4+N System: In this mode, the interface works with the analogic street panel system
o
where the call is generated via a single cable. In 4+n there is only one operating mode:
- Single Call (SCM). The interface acts as a telephone terminal that responds to a
single call from the street panels.
VDS System: In this mode, the interface works with the VDS system, where it performs
o
the call via a command. VDS has the option to work in two different operating modes:
- Single Call (SCM). The interface acts as a telephone terminal that responds to a
single call from the entry panels.
- Multiple Call (MCM). The interface acts as a gateway between the VDS system
and a telephone system (telephone switchboard or a telephone line), converting
the VDS calls to telephone numbers, that is, multi-calling, to make different calls to
different extensions or telephones relative to the VDS call generated on the entry
panel. This way you can make calls to different extensions in an offi ce from the
entry panel, not just to one, like in the previous models.
