Creating Data Hunt Groups 5
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 Ascend Pipeline 25
or 50). 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 5
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.
