HUNT GROUPS

If a site has a large number of hunt groups used concurrently (e.g., in a call center environment),
then the site should be equipped with a PS-1. The number of hunt groups, combined with
medium to high call traffic that rings into a hunt group, greatly increases the need for a PS-1.

ALL-RING HUNT GROUP MEMBERS

If a site has all-ring hunt groups containing more than 30 members, then the site should be
equipped with a PS-1. The number of all-ring hunt groups, combined with medium to high call
traffic that rings into an all-ring hunt group, greatly increases the need for a PS-1.

ALL-PAGES

If a site performs a lot of paging to page zones containing more than 30 destinations, then it
should be equipped with a PS-1.

PHONES

If a site has more than 175 phones with medium call traffic, then it is a good candidate for a
PS-1. If a site has more than 150 phones with high call traffic, then it should be equipped with
a PS-1. This applies to digital telephones, IP phones, SIP phones, and single-line phones.

TRUNKS

If a site uses more than 50 trunks concurrently, then this could be a good indication that the
site has high call traffic; therefore, the site should be equipped with a PS-1.

IP DEVICES

If a site has more than 150 total IP devices with medium call traffic, then it may be a good
candidate for a PS-1. If a site has more than 100 total IP devices with high call traffic, then it
should be equipped with a PS-1. IP devices include IP phones, SIP phones, IP trunks, IP
networking, SIP trunks, and SIP voice mail ports.

HUB NODE IN A NETWORKED SYSTEM

If a site is equipped with multiple nodes, the hub (main) node may be a good candidate for a
PS-1. A node is considered to be a hub node if it is a PSTN gateway for the other nodes in the
network, or the node provides access to the rest of the networked nodes for more than one
other node. If the call traffic into the hub node is medium to high, then the node should be
equipped with a PS-1.
