Creating Data Hunt Groups

Creating Data Hunt Groups
Use these instructions if the system has a group of modems or ISDN terminal
adapters.
DHGs are data calling groups that provide uniform call distribution among a
group of modems or a group of ISDN terminal adapters (such as the
ExpressRoute 1000 or 7500B data module). DHGs support the following:
Modem pools
Dedicated lines for data service
A local host computer
Workstation that functions as a gateway on a LAN
For more information, see the "Planning Overview," earlier in this chapter, or
refer to Equipment and Operations . For information on modem pools, see
application note, MERLIN LEGEND Communications System Modem Pooling .

Guidelines

Use the following guidelines for the procedure in this section:
Members of a DHG must be extension jacks of the same type: all analog
or all MLX.
You can assign up to 32 DHGs or calling groups, or a combination of
both types. Each DHG can have a maximum of 20 members and each
data station can be a member of only one DHG.
You can designate particular lines/trunks or pools (Hybrid/PBX mode
only) to ring directly into a DHG. However, incoming calls on a given
line/trunk can be directed to only one DHG.
Extension numbers 770 through 791 and 7920 through 7929 are reserved
automatically for calling groups and DHGs. If you want to change the
extension numbers assigned to a DHG, see the information about
reassigning extension numbers described in Chapter 2, "Control Unit
Configuration." The same considerations apply to data stations and voice
extensions.
