CONFIGURING RESOURCES AND LINES

Lines

CALL SCREENING METHODS

For basic rate lines only. If you select a line interface type of point-multipoint, choose one of the following call screening methods: none, subaddress, or telephone number. The paragraphs below define each method.

1.None

All calls will be accepted.

2.Subaddress

Uses a configured subaddress for this site. If the subaddress method is chosen, and a subaddress has not been configured for this site, an error message will be displayed. You must either choose another method, or configure a subaddress for this site.

3.Telephone Number

Telephone number(s) for your site used for call screening. Only calls directed to that specific telephone number will be accepted. If there is more than one, enter the list of telephone numbers separated by commas. After entering the telephone numbers, you will then be asked to enter the maximum number of digits (starting at the rightmost digit) to be verified.

Note: If the telephone number(s) entered here do not exactly match the number(s) for the site, you will be warned at this time. (The number of digits compared will be the number of digits you chose to use for verification.)

DATA LINKS

A data link is a data communications link to the telephone switch. Your Carrier Service can provide you with the data link values you need to configure. All switch types, except the DMS100 and the NI-1, require a single data link per line. The NI-1 switch type can have either one or two data links per line. The DMS100s generally require two data links per line, one for each B channel. For both NI-1 and DMS100 switch types, contact your Service Provider for the number of data links required.

The table below summarizes the number of data links and SPIDs that are required for each switch type.

Switch Type	Number of Data	Number of SPIDs	Number of
	Links		Directory Numbers
DMS100 custom	2	2	2
NI-1	1 or 2	1 or 2	1 or 2
all other	1	0	0

When adding a data link for BRI lines, designate whether to use Automatic TEI Negotiation. Automatic TEI Negotiation is used UNLESS this is a point-to-point NTT line. If you do not use Automatic TEI Negotiation, a TEI value is required. The default TEI value is 0, which is normally correct for a point-to-point NTT line. For PRI lines, use the default TEI value of 0.

Data links are handled differently for DMS and NI-1 switches. For most switches, the BRI line has only one phone number (for the Data Link), but it can handle two calls (one for each bearer
