ADTRAN TSU IQ+, 1204002L2 user manual Call Screening, PRI Options

Chapter 8. Configuring DBU Options

B-Channel Bit Rate (B-CH BIT RATE)

Select the channel bit rate for the ISDN service. Select 64K unless your service only provides 56K.

Number of B-Channels (NUM B-CHANNELS)

Select the number of B-channels supported by the ISDN service.

Select 2 if bonding is used.

SPID 1 and 2

Enter the service profile identifier (SPID) for both B-channels. The SPID is a sequence of digits identifying ISDN terminal equipment to the ISDN switch when more than one ISDN set has been attached to the same central office line. The SPID is assigned by the telco when the ISDN line is installed and normally resembles the phone number.

Only the Lucent 5ESS switch is capable of recognizing a point-to- point configuration, eliminating the need for a SPID. All other switch types require a SPID.

LDN 1and 2

Enter the LDNs for both B-channels. The LDNs are assigned by the telco when the ISDN line is installed.

CALL SCREENING

If CALL SCREENING is set to ENABLE, the TSU IQ+ will only accept incoming calls from the numbers entered in the NUMBER 1 through NUMBER 5 fields. Calls from any other number or from an unidentifiable number are rejected (for BRI card only).

The PRI OPTIONS field is available when the PRI DBU card is installed. The following options are available.
