LAN services
!WARNING:Do not enable ETR on ports used for DID.
An outside telephone exchange can be connected to the trunk port, and an analog telephone can be connected to the line port. All calls are then directed by the analog relay between the outside line and the analog telephone. A
The contact closure feature is a controllable relay providing dry contacts for various applications. To implement the contact closure feature, connect an Avaya Partner Contact Closure Adjunct box to the CCA port on the G250/G350 chassis. The adjunct box provides two contact closures that can be operated in either a “normally closed” or “normally open” state. The contact closures can control devices such as devices that automatically lock or unlock doors or voice recording units. The CCA port can be configured so that the connected devices can be controlled by an end device, such as a telephone. For example, a user can unlock a door by keying a sequence into a telephone keypad.
Fax, modem, TTY over IPThe G250/G350 supports fax, modem, and TTY over IP.
LAN services
You can use both the Avaya G250 and Avaya G350 Media Gateways as a LAN switch. You can also integrate the G250/G350 into an existing LAN.
Physical media
The G350 provides LAN services through the following Ethernet ports for the connection of local data devices:
●Switched LAN ports. Configurable switched Ethernet ports on the MM314 media module (see MM314 LAN media module on page 32) and the MM316 media module (see MM316 LAN media module on page 33). The switched Ethernet ports support HP
