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.)

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.
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
