Features
Integrated Services Digital Network (ISDN)
84 Strata CTX General Description 10/04
Integrated Services Digital Network (ISDN)
System Availability: Strata CTX100, CTX670
ISDN is a set of integrated telecommunications services, available over the public
telecommunications networks. ISDN makes it possible to send, receive and modify information
using telephone lines in ways that were not previously possible, such as:
• Dynamic use of individual or groups of standard (POTS), DID, Tie, FX, WATS, 800 lines on an
as-needed basis
• Much faster call setup and data transfer up to 128Kbps
• Multi-purpose line use, including sharing lines for voice, data, fax, and video
• DID functionality based on the number dialed; without needing to reserve a block of numbers
• 2-B channel transfer: Allow two external PRI line calls conected to a station conference to be
released from the CTX and reconnected by the PSTN when the station drops out of the
conference. Requires CTX R2.0 or above and special ordering from the ISDN provider.
ISDN service comes in two forms:
• Primary Rate Interface (PRI) supports simultaneous voice or data connections (eight, 16 or
23). PRI is similar to digital T1 service and uses two pairs of wires from your phone company.
The RPTU circuit card supports PRI on the Strata CTX.
• Basic Rate Interface (BRI) supports up to two simultaneous connections using a single pair of
wires. The Strata CTX BRI cards support both station side and trunk side connections. Strata
CTX systems also support BRI interface from the public network as a CO line service. There
are two types of ISDN BRI interfaces: S/T type (via RBSU/RBSS) and the
U-type (via RBUU/RBUS).
Least Cost Routing (LCR)
System Availability: All systems
Least Cost Routing chooses the most appropriate route over which to connect an outgoing call
based on the following:
• Dialed Digits
•Time of Day
• Type of Day (Business, Weekend, Holiday)
• LCR group of the caller
The combination of routing tables, indices, route definitions and time-of-day qualifiers can
produce up to 75 million combinations. Routing changes automatically for each type of day,
according to the time of day. This schedule is independent of the Day/Night mode schedule which
applies to ringing and CO assignments.
Line Buttons
Telephone buttons that are used for making and receiving outside calls are referred to as Line (or
CO Line) buttons. (For information on various [DN] buttons, refer to “Directory Numbers” on
page 68.) The Strata CTX supports the following types of line buttons:
