Definition of terms
The following terms used in this manual are used during the configuration process.
Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) -
A digital
communication medium that operates over existing analog telephone lines provided by the
telephone company. ISDN BRI provides two 64 KBPS Bearer (B) channels for voice and data
and one 16 KBPS D channel for customer and call information. ISDN BRI is usually denoted
as 2B+D.
Service Profile Identifiers (SPIDs) –
These are numbers assigned by the ISDN service
provider that identify the ISDN B channels. The SPID format is generally the ISDN telephone
number with several numbers added to it. Depending on the switch type supporting your
ISDN BRI line, your ISDN line might be assigned none, one, or two SPIDs. They are
assigned only in North America.
Directory numbers
- The ISDN equivalent of standard telephone numbers. These are the
numbers the access device dials to connect to a remote access device or the numbers that
users dial to connect to a POTS or telephone line attached to the local access device. In order
to use the OmniConnect access device’s powerful call management features to the fullest
extent, it is recommended that multiple Directory Numbers or DNs are for the ISDN BRI line
are ordered along with the line. ISDN BRI lines are generally assigned two local directory
numbers, one for each B channel. However, most Bell Operating Companies and telecom
providers allow up to 8 or 16 Directory Numbers assigned to each line.
Access code
- A number that must be dialed preceding the telephone number to dial outside
of a specific telephone system, such as a Centrex system. Examples of this are the ‘9’ that
precedes the telephone number.
Internet Protocol (IP) address
- A network address that uniquely identifies a device on an IP
network. This type of address consists of 4 bytes, represented as decimal values, separated by
periods, e.g., 192.168.2.143.
Media Access Control (MAC) address
- This 48-bit address is assigned by the device
manufacturer to define the Ethernet address of the device. All OmniConnect access devices
have MAC addresses of the form 00-10-98-xx-xx-xx. Each byte is represented as a
conventional two digit hexadecimal number.
Point-to-Point Protocol (PPP)
- A serial protocol defined in RFC 1661 that is used to
provide point-to-point connectivity over serial links.
