Safety Precautions
To limit the risk of personal injury, always follow these precautions before connecting telephone
circuits:
! Never install telephone wiring during a lightning storm.
! Never install telephone jacks in a wet location unless the jack is specifically designed for wet
locations.
! Never touch non-insulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
Use caution when installing or modifying telephone lines.
Digital Keysets
You can connect OfficeServ500 keysets, DCS (“Euro”) keysets or i DCS Series keysets to the
telephone system. For Internet (IP) phones, refer to IP Phones , below.
NOTE: OfficeServ500 is a self-configuring system. If you connect, say, a 12-button Euro
keyset to a DLI port that previously had a 24-button Euro keyset installed, the existing data
will be rewritten with 12-button keyset default data (MMC 723). This can be avoided if you
first SAVE the keyset data using MMC 720. This rule also applies to all keysets.
Using one pair twisted #24 AWG (0.5mm) or #26 AWG (0.4mm) jumper wire, cross-connect each
keyset to the DLI port (
Figures 7–1a and 7–1b ) or plug into the keyset daughterboard of your
choice (see Chapter 9 ).
CAUTION: To reduce the risk of fire, use only #26 AWG (0.4mm) or larger telecomm-
unication line cord.
IP Phones
An IP phone allows calls through the Ethernet LAN network to other devices (such as a digital
phone) connected to the telephone system. The connection between the device and the IP
phone is established using the IP address through the LAN connected to the MCP2 card. When
connected, a device converts analogue voice data to PCM voice data, and sends it to the MGI
card. The PCM voice data is converted to packet data by the MGI card, and transferred to the IP
phone. The IP phone converts the packet voice data to analogue voice data sent through the
handset or speaker. Analogue voice data entered into the IP phone is likewise converted to
packet data, transferred to the MGI card, converted to PCM voice data, transferred to the receiv-
ing device through the 16DLI card, and finally converted to analogue voice data at the destina-
tion.
