Enabling a line for Clock Source use
To specify which lines can provide Clock Source, set the following parameter located in
Net/E1 > Line Config > Line Config profile > Line N subprofile:
For detailed information about each parameter, see the MAX Reference.
Setting triggers for call-completed information
If you enable the overlap receiving feature, your MAX unit can gather the complete called
number from the network switch through a series of information messages, and can therefore
support features such as called-number authentication. Provide information about the called
number itself by setting PRI Prefix # and Trailing Digits. Once the MAX receives the called
number, the PRI Prefix # value determines the number of digits the MAX matches as the prefix
to the number. The Trailing Digits number indicates the number of digits the MAX requires to
indicate the end of a called number. Open Net/E1 > Line Config > Line Config profile > Line N
profile and set the following parameters:
Parameter Specifies
Clock Source That the line can (Yes) or cannot (No) be used as the clock source for
timing synchronous transmissions between the sending and the
receiving device. A MAX unit only has one clock source. The first line
that comes up is the clock source for all the lines. If you set this
parameter to No, the MAX uses its internal clock.
Parameter Specifies
Overlap Receiving Whether or not to determine if a called number is complete for
incoming calls.
PRI Prefix # Portion of the line’s telephone number to be used when matching the
called number in the Setup message from the network.
Trailing Digits Number of digits required to follow the prefix number for the unit to
consider the called number complete.
T302 Timer Number of milliseconds the system waits for additional called number
information for an incoming call.
After receiving the call, the MAX begins collecting the trailing digit
information, and for each call setup message from the switch that does
not include the Sending Complete Information element, it starts the
T302 timer. The MAX stops the timer when it receives a message that
includes the Sending Complete Information element. The MAX
assumes there are no more trailing digit digits to collect when the
T302 timer stops or expires.
