• Line Type - Selects the line type of Digital Interface: T1 or E1. If the T1/E1 WAN interface
card can be dynamically configured as a T1 or E1, then this attribute is configurable; otherwise,
it is read-only.
• Voice Coding Law - The Law command is used to set the voice coding law for this Digital
Interface to either Mu-Law or A-Law. Typically, Mu-Law is used with T1, while A-Law is used
with E1.
• Signaling Protocol - CAS (Channel Associated Signaling) carries signaling information within
the data channels of a T1 line (in band) rather than on a separate control channel. CAS
signaling is also used to carry 911 emergency data such as telephone number and location
information. CAS Signaling is primarily used on T1 lines (and for the most part E&M is the
Signaling Type of choice), and R2 is CAS Signaling on an E1 line.If you select CAS, you will
also need to select a Signaling Type,
ISDN (Integrated Services Digital Network) is an international standard for end-to-end digital
transmission of voice, data, and signaling. ISDN uses existing phone lines, but does require
specialized equipment. The Basic Rate Interface (BRI) consists of two 64 kbps plus another
lower rate channel to handle signaling. Primary Rate Interface (PRI) consists of 23 channels
plus a signaling channel. If you select ISDN, you will need to select the PRI protocol.
