IP400 PRI Cards (T1/E1/E1R2)
Available in single and dual versions the IP400 PRI card provides single and dual primary rate trunk interfaces
respectively. The PRI is available in T1, E1 and E1R2 MFC variants depending on the territory. The dual version
is only supported on the IP412, in slot A of the IP406 V2 and in the IP500 using an IP500 Legacy Card Carrier.
The Small Office Edition only supports the single T1 PRI card (not E1 or E1R2).
Details of the supported ISDN supplementary services and protocols for each PRI are given in the 'Public and
Private Voice Networks' section.
T1 trunk cards incorporate an integrated CSU/DSU. The CSU function allows the trunk to be put in loop-back
mode for testing purposes. This can be set manually, using the monitor application, or automatically from a
Central Office sending a Line Loop Back (LLB) pattern. The DSU function allows the T1 trunk to be shared
between data and voice services.
IP400 Universal Quad Analog Trunk (LS) Card
This card provides four analog trunk ports. These are 2-wire loop start interfaces and are available in all
territories. This card supports Caller ID where provided. With IP Office R3.1 and later, this module supports
optional 16ms echo cancellation.
Please note that ground start analog trunks are supported via the IP Office Analog Trunk 16 Expansion Module.
