Digital Subscriber Line (DSL) is a family of technologies that transports data over existing twisted-pair

service) to deliver broadband applications, such as multimedia and video, over the local loop (or last
mile) that connects the telephone company’s central office to customer sites.

SPID1 Applies only when you select Basic-DMS-100, Basic-NI, or Basic-5ess
as the switch type.
The service provider identifier (SPID) for the ISDN service to which
the interface subscribes. Some service providers in North America
assign SPIDs to ISDN devices when you first subscribe to an ISDN
service. If you are using a service provider that requires SPIDs, your
ISDN device cannot place or receive calls until it sends a valid assigned
SPID to the service provider when accessing the switch to initialize the
connection.
Valid SPIDs can contain up to 20 characters, including spaces and
special characters.
Note We recommend that you do not enter a SPID for interfaces
using the AT&T 5ESS switch type, even though they are
supported.
SPID2 Applies only when you select DMS-100 or NI as the switch type.
The service provider identifier (SPID) for a second ISDN service to
which the interface subscribes. Valid SPIDs can contain up to 20
alphanumeric characters (no spaces are permitted).
