Important PRI Channel Information

Outgoing Call. For an outgoing call, the ViewStation FX or VS4000 system uses the first active and available channel starting with the lowest number from the channel range (1-23 for a PRI T1 and 1-30 for a PRI E1). If an additional channel is needed, the system chooses the next incremental number. For example, if channels 1 through 7 are inactive, but 8 is active and available, then 8 is the first channel that can be used by the ViewStation ViewStation FX or VS4000 system to place an outgoing call. If an additional channel is needed, the system will use the next available active channel in the range (which could be 9, and so on). Incoming Calls. For incoming calls, the ViewStation FX or VS4000 system may use the highest numbered channel in the range and, if needed, proceed to the next channel number in a decremental order, depending on the type of third-party equipment attached to the system. For example, an incoming call arrives on channel 23, then 22, 21, and so on.

Dedicated full PRI T1 or E1 Line: All channels should be active for a full T1 or E1 line dedicated to your ViewStation FX or VS4000 system.

Fractional PRI T1 or E1: Channel selection should be handled by your PRI network administrator.

PRI E1 Channel Information. The PRI Status screen (for E1) shows 30 channels. However, E1 trunk lines have 32 timeslots, numbered 0 - 31. Timeslot 0 is used for framing, and timeslot 16 is used for call signaling (the D channel). The remaining 30 timeslots are used as bearer (data) channels. In call signaling between our equipment and the switch, these channels are numbered 1-15,
