Enhanced Tip Ring Ports
There are eight Enhanced Tip Ring ports per processor module and 362EC
expansion module. The top six station ports support only Enhanced Tip Ring
devices and the bottom two ports support both Enhanced Tip Ring and Tip Ring
devices. Connect headsets and other adjunct equipment that do not require
incoming ringing to any port or through the AUX jack on a PARTNER Endeavor
telephone.
NOTE:
Doorphones should not be connected to an Enhanced Tip Ring only port
since doorphones rely on receiving a forward disconnect signal to
disconnect a call. If a Tip Ring device is connected to an Enhanced Tip Ring
only port, a forward disconnect signal is not sent and ringing is not heard at
that port.
Auxiliary Equipment
You can connect many types of telecommunications devices to your system
without expensive adapters or additional phone lines—for example, answering
machines, credit card scanners, and fax machines. Many industry-standard,
single-line devices will work with the system regardless of the manufacturer.
For more information, refer to the list in Chapter 4 or contact your Lucent
Technologies Representative or local Authorized Dealer. Also, see Chapter 4 for
advice on setting up auxiliary equipment to work effectively with the system.
Requirements
An industry-standard device must meet the following conditions:
■ It must be non-proprietary. That is, it cannot be made specifically for use on
a particular telephone system. (For example, you cannot connect a Lucent
Technologies MERLIN LEGEND® Communication System phone,
because it is specifically designed for use on a MERLIN LEGEND
Communication System.)
■ Its Ringer Equivalence Number (REN
1
) cannot be greater than 2.0. (The
REN is shown on a label on the device, usually on the bottom.)
■ You can connect a standard two-line device to the system, but for best
results it should be installed and used as if it were a single-line device.
1. REN is a measure of the power it takes to ring a phone. The typical home phone line supports
4.0–5.0 RENs; each extension jack in your system handles up to 2.0 RENs.
