• Call-By-Call Service Selection (CBC) - This feature allows telephone users to select the
ISDN network services that they wish to use on a per call basis.
• DID Calling Party Number Forwarding - Outgoing CPN delivers the calling party’s DID
number to the Network when the call has been identified as a call from a device with an
associated DID number instead of delivering the main directory number associated with
the system.
• Equal Access to Interexchange Carriers - The system provides a carrier access code
to the ISDN Network Gateway which identifies to the Central Office which Interexchange
Carrier is to receive the call. The system outpulses a digit string which includes a carrier
access code, followed by an identification number, followed by the called number.
• Min/Max - This feature allows a customer to control incoming and outgoing call traffic.
Minimums are assigned to ensure that a particular type of call (such as INWATS) always
has a set number of lines available. Maximums are assigned to limit certain types of calls,
i.e., OUTWATS. This ensures that resources are not used up by a single type of call.
Different Min/Max databases can be created for different times of the day or for special
occasions such as telethons or infomercials.
• Auto Min/Max - This feature provides user programmable time-of-day automatic control
of Min/Max parameters.
• NFAS (Non-Facility Associated signaling) - NFAS allows you to use a single D-channel
to handle the signaling requirements for a group of PRI links that all use the same Protocol.
This feature eliminates the need to purchase a D-channel for each link. NFAS is mainly
for North America.
• D-Channel Backup - This feature is used for signaling to establish and maintain the
circuit, and to send user data. D-channel Backup provides an alternate D-channel for calls
related to NFAS. If the active D-channel fails, the system switches to the backup D-channel
to support call processing. This functionality is mainly for North America. NFAS is required
in order to program D-channel Backup.
• Q.SIG - This feature provides the ability to connect Q.SIG compatible PBXs from different
vendors together to form a private network and to connect the SX-200 to the SX-2000
LIGHT system or any other Q.SIG compatible PBX. Q.SIG features that are supported
include Calling Name for incoming calls, Message Waiting Indication, Call Transfer, Call
Diversion, and Path Replacement.
• Remote LAN Access - This feature provides LAN access to the wide area network (WAN)
for both incoming and outgoing calls through LAN servers (routers or bridges).
• Multiple Variants and Configurations - This feature provides the ability to run multiple
protocol variants and program multiple configurations on the two links of the PRI Gateway
through the IMAT application. The option to run multiple variants allows you to connect
the PRI Gateway to two different CO switches. The option to run multiple configurations
allows you to program Network-side on one link of the PRI Gateway and program User-side
on the other link of the PRI Gateway. For more information on programming multiple
variants and configurations, refer to the IMAT online Help.
