CALLED # PLAN
The Called Number Plan refers to the type of numbering plan used to reach the device you are
calling. The options are unkwn, isdn, phone and privt. Your carrier will provide more detail
about this option.
CHANNEL RATE
The Channel Rate selection specifies the bandwidth to be used by the call. Different carriers
support different rates, so it is important to check with your carrier before setting rates greater
than 64Kbps. When using any Channel Rate other than MRate, the system knows the size of
the bandwidth required and will automatically select the rate multiplier. If MRate is selected,
the rate multiplier must be entered by the user.
The u (unrestricted) and r (restricted) in these selections are for data calls. An unrestricted call
means the user can send any type of data information in the circuit. A restricted call means the
user is responsible for maintaining the ones-density-integrity of the T1 data stream.
Note: Channel Rates of 1536r and 1536u require the use of NFAS.
If the IMUX CALL field is set to yes (see below), the channel rate shows either 56, 64 or H0
(384K).
RATE MULTIPLIER
The Rate Multiplier parameter is automatically set depending upon the Channel Rate (other
than MRate or an IMUX call) chosen in the previous paragraph. Valid entries for MRate are
2-24. If an incorrect rate multiplier is input, the carrier equipment will reject the call.
If the IMUX CALL field is set to yes (see below), the channel rate shows either 56, 64 or H0
(384K).
IMUX CALL
The IMUX Call field indicates whether this is an IMUX call or a regular ISDN call. The
options are no and yes. If yes is selected, the Channel Rate and Rate Multiplier selections will
change (see above).
Since IMUX calls cannot be broadcast, if IMUX call is yes, the user will not be able to use the
Broadcast Phones option mentioned later in this section.
