14.3.17 The CRN Command

The Call Request with Number command is sent form the DTE to the HSU card to request a
particular number to be dialed. The DTE may include parameters setting the call type, rate
bandwidth range, etc.
Other than the new phone number, type and bandwidth, the CRN command uses the data form
the currently loaded HSU call profile.

14.3.18 The SCT Parameter

The Switched Call Type parameter to the CRN command selects the type of call made. Call
types define the data rate of a single channel, the type of carrier service for the call and indicate
if multiple channels can be aggregated for this call. If this parameter is not specified, the value
in the HSU Card current call profile is used.

14.3.19 The BWR Parameter

The Bandwidth Request parameter to the CRN command selects the desired bandwidth in
terms of the minimum and maximum number of channels the HSU Card can allocate to a call.
This parameter is ignored if the SCT does not allow aggregating channels (if N is specified for
the SCT parameter). If this parameter is not specified, the value in the HSU Card current call
profile is used.

14.3.19.1 Example

An example of a CRN command (using the semicolon character as afield separator) is:
CRN5103537728;SCT56;BWR1-24.
This example commands the system to call the number 510-3537128 using Switched 56kbps
and Bandwidth request from 1 to 24 channels.

14.3.20 The CRS Command

The Call Request with Memory Address dials the number and uses all of the parameters on
the call profile from those stored on the Interface card. This command changes the current
loaded call profile on the HSU card.
