Considerations
Modem Pooling provides a pool of conversion resources that increases data call flexibility. Conversion resources allow analog data endpoints, using modems, to communicate with digital data endpoints (using data modules). Also, modem pooling reduces costs by sharing resources.
Interactions
●Automatic Route Selection: Data calls may be queued. See Table
● Calling Restrictions: | If a terminal is toll or access restricted, the modem resource |
is released when the user | receives intercept treatment. |
●Direct Group Calling: Modem pooling supports calls to data endpoints that are part of a DGC group. While an incoming data call is in the DGC group queue, the caller hears Ringback Tone. The conversion resource is inserted if the call is completed to a digital endpoint.
●Station Hunting: Modem Pooling supports calls to data endpoints that are part of a station hunting group.
● SMDR: SMDR records | do not reflect modem resource usage. | Interpremises data |
calls using a conversion | resource are reported as data calls on the | SMDR call record. |
Administration Requirements
System (Pooled Modems):
●Modem Request Code
conversion resource on a data call originated at an analog data endpoint.
● Receiver Responds To | Remote | Loop (Yes, | No) | - Default | = Yes. When active, Data |
Set Ready is asserted | when the | modem is | in an | analog loop | test mode. |
●Disconnect On Loss Of Carrier (Yes, No) - Default = Yes. When active, a loss of the
received carrier will cause the modem to terminate the call.
●
●Disconnect On Received Space (Yes, No) - Default = Yes. When active, the modem will disconnect after receiving a “Space” signal of approximately two seconds duration.
●Send Space On Disconnect (Yes, No) - Default = Yes. When active, the modem, upon receiving a negation of Data Terminal Ready, sends approximately four seconds of “Space” signal and then disconnects. Without this option active, the modem, upon receiving a negation of the Data Terminal Ready signal, disconnects immediately.
