Server Cards 7-11
IMUX Card Inverse Multiplexer (IMUX) Card Settings
DCHAN
The D Channel number identifies which D Channel to route all outgoing calls that use this call
profile. The options are numbers 1-8.
CALLED #
The Called Number is the full telephone number of the device you are calling. Up to 25
numeric characters are allowed, although most calls use only ten digits. This parameter can be
overridden on a call-by-call basis when RS366 or V.25bis dialing is used with the Model 8213
HSU card.
CALLED # TYPE
The Called Number Type identifies the type of network used to reach the called phone number.
The options are natnl for domestic calls, intnl for international calls, and sbscr for Virtual
Private Network (VPN) calls. Your carrier will provide more detail about this option.
CALLED # PLAN
The Called Number Plan refers to the type of numbering plan used to reach 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 64 Kbps. 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’ and “r” in these selections are for unrestricted and restricted 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).
