Alternate Routing - PRI A-76

A-76 Alternate Routing - PRI

General Description

This featur e is pr ovi de d with LC R, whic h a uto ma ti c al ly r out e s IS DN outg oi n g on- n et c a lls ov e r a lter na te faci li ti es
when the first-choi ce trunk g roup is bus y. The user selects the firs t-choic e route by dialing t he corre sponding ac cess
code. The equipment then routes the call through alternate trunk groups if the first is busy. The NEAX2400 IMX
will also add or delete digits, when necessary, to complete the call to the desired station.

Operating Procedure

No manual operation is required.

Service Conditions

1. A step-by-step explanation that provides a clearer understanding of how the NEAX2400 IMX
accomplishes Least Cost Rout ing follows:

a.) If dialing a toll or local call (NPA-XXX or NXX-XXXX), routing begins with translation of

three-digit (NPA or NXX) area or office code. In the case of specific numbers, this translation
may result in the im me dia te sel e ctio n of the th re e- di g it r outin g patt e rns . If t he numb er dia le d is an
NPA and six-digit translation is required, the NXX code is verified in the SCC (XX) or the FX
(XX) Table. If the NXX is not located in either table, see part C of this Service Condition. There
are a maximum of 256 Outgoing Pattern Routing (OPR) Tables with a maximum of 8 routes for
selection.

Note: SCC (XX) is a Special Common Carrier NXX Translation Table. FX (XX) is the FX NXX Translation Table.

b.) First choice route option is an NPA pattern that will most often be a Specialized Common Carri er.

If a trunk is available in this group, further digit translation is required to determine whether the
called number is served by the carrier. NXX digit translation is also required in instances where a
call is routed over a tie or FX trunk. For these purposes, 256 NXX patterns are available.

c.) In the case of Specialized Common Carriers, associated NXX patterns will return a Yes/No

answer to the PBX, indicating whether or not the dialed number is within the designated service
area of the selected SCC. If service is available, the PBX will seize the trunk and complete the
connection. If th e No answer i s ret urned, the PBX searches for the next availabl e trun k group.

d.) Calls routed over FX trunk groups may re quire outpuls ing o f prefix digit “a,” depending upon the

NXX number dialed. For this purpose, another group of associated NXX patterns can be used,
operating on the same Yes/No principle. A Yes answer returned to the PBX in this instance
results in prefix “1” being added automatically before sending digits to the called Central Office.

e.) In a circumstance where the selected route is an FX trunk group, NXX translation can be used to

either allow or disallow the connection. This is accomplished using Yes/No answer from a
designated group of NXX patterns, and enables calls to selected Central Office areas to be
effectively restricted to only the most economical routes.

2. In certain cases, three- and six-digit translation provide sufficient information for identification of the
service area; 256 separate Outgoing Routing Patterns are provided for this.

3. Up to eight trunk routes can be in each Outgoing Routing Pattern.

4. STATION MESSAGE DETAIL RECORDING (SMDR) [S-10] can be used in conjunction with Least
Cost Routing. The route selected by the PBX is recorded by the SMDR unit.

5. Tie lines can be included in route patterns.

6. Application of NXX patterns provides for inclusion of multiple common carriers serving different areas.

NEAX2400 IMX ISDN Features and Specifications
NDA-24281, Issue 1

Page 1

A-76 Alternate Routing - PRI

Service Conditions (cont’d)

7. When a Tie trunk requiring an off-net connecti on to the local Centr al Office is included as a route option,
the NEAX2400 IMX can provide a 2.8 second prepause before sending out the selecting signal.

8. Senders (dial pulse or tone) are provided with this feature for dialing.

9. Pre-translation capability minimizes waiting time after dialing. After enough digits are collected to
determine a route, the system starts outpulsing before the station completes dialing the entire called
number.

10. When Least Cost Routing is provide d, the Atten dant cannot pass dial ton e to a sta tion. The des ired number
must be dialed by the Attendant.

11. Stations having different Route Restr iction Classes, but using the same Le ast Cost Routing pa ttern, c an be
denied access to the last choice trunk route(s) in that pattern. Route Restriction Classes may be set up so
that a station dialing an area code can use WATS, FX, and DDD; or only the WATS line, if such an
arrangement is des ir ed. This is a form of forced Least Cost Routing .

12. NXX patterns may be programmed to restrict all stations in the system from completing calls to specific
NXX numbers over FX trunks.

13. The system includes the ability to detect a dialed DDD number and compare it with a DDD list table to
determine if the call is directed to a facility served by the trunk network. If the dialed number is found in
the DDD list table, a transla tion is provide d to the seve n-digit, on- net number (AFC- XXXX) served by th e
Tie trunk. This allows an expensive public network dialed number to be trapped and automatically
diverted to an available leased facility. If a Tie trunk is not available, the call is routed as dialed.

14. The NEAX2400 IMX is capable of converting a maximum of 24 receiving digits into a required 24-digit
number. In terd igit al p ause s ca n be in sert ed w hen ever nec essa ry. Thi s pr ovid es f or an ex tre mely fle xib le
numbering plan for a complex network.

15. CALL-BY-CALL SERVICE SELECTION [C-105] is available on a provisionary basis.

16. When activating thi s feature via the FCCS network, only Physical Tele phone Number may be used.

Establish a data call using the procedures described in the ASYNCHRONOUS DATA SWITCHING [A-24] and
SYNCHRONOUS DATA SWITCHING [S-29] feature descriptions.

When the data connection has been established, information transfer between the two connected DTEs is completely
transparent at speeds up to 9.6 kbps asynchronous and 56 kbps synchronous. The NEAX2400 IMX does not alter
the data in a n y ma nner.

Service Conditions

1. During data call origination and termination involving a Data Adapter or Data Module, certain character
string sequences are exchanged as part of the call setup process.

2. After the data connection is established, the Data Module awaits entry of the ESC character followed
immediately by -DM as a disconnect request from the DTE.

3. Data transparency does not imply speed and code conversion. If dissimilar devices cannot communicate
when connected directly to each other, they will not be able to communicate via the NEAX2400 IMX.

Data Communications - PRI D-121

Service Conditions

Modem and Modem Pool Calls

1. A total of eight modem pool groups may be assigned: eight incoming, eight outgoing, eight bothway, or
any combination thereof.

2. Modems must be compatible.

3. Modems in a modem pool may be per manentl y assi gned, e nd-to- end, t o a PRI channe l on a dedic ated l ine
basis; otherwise, modem pools are normally dynamically assigned on a switched basis to an incoming or
outgoing data caller on a PRI channel. In this case, the same PRI channels are available for voice also.

4. The maximum modem speed is 9600 bps. Both asynchronous and synchronous modems may be used in
the modem pool. Modems connected to analog extensions may b e asynchronou s or synchronous.

Unrestricted Data

1. The following communication speeds are supported:

Asynchronous: 50 ~ 9600 bps
Synchronous: 2.4K, 4.8K, 9.6K, and 48K bps

2. Attribute Data for remote AUTOMATIC ATTRIBUTE DATA RECOGNITION [A-40] will not be
passed over a digital link modem connections.

3. Pooled modems and modems connected to analog stations may be used on PRI channels when a straight
digital data connection is not required. With PRI, modem pooling will always be automatic when
accessing a PRI channel by se tting the AMND command of the MAT to 0. If AMND is set to 1, th e channel
will either use modem pooling or a straight digital path, depending on the number dialed. This number is
compared with the PRI link to the other end switch to determine if an analog or digital extension is being
called.

4. PRI re qu ire s on e D- ch a nne l of a 24 -c h ann e l di git al lin e for out-of -band signaling. The other 23 chan nels
(B-channels) can be used for voice or data, or both.

D-137 Direct-In Termination (DIT) - PRI

General Description

This feature automatically routes incoming network exchange calls from an ISDN network and public/private
telecommunication network directly to a preselected station without Attendant assistance. The call can then be
processed by the called party. THREE-WAY CALLING [T-2], CALL TRANSFER - ATTENDANT [C-10], etc.,
are handled in the sa me manner as any normal trunk call.

Operating Procedure

The calling part y, outsi de the syste m, dials th e tel epho ne number as usua l. Ho wever, t he cal l is a nswered direc tly a t
a predetermined station, bypassing the ATTENDANT CONSOLE [A-3].

Service Conditions

1. Any group(s) of trunks can be used, up to the maximum capacity of the NEAX2400 IMX.

2. Bothway trunks can be used for DIRECT-IN TERMINATION, but incoming only trunks are
recommended.

3. It is not necessary to order special DID trunks to the telephone company as is required with DIRECT
INWARD DIALING [D-8]. However, care should be exe rc ise d in the application of Ce nt ral Off ice trunk
hunting.

4. If the called station is busy, that call is kept ringing until the called station becomes idle, or is forwarded
to the ATTENDANT CONSOLE [A-3].

5. If there is no answer at a station, the calling party will continuously receive ringback tone. There is no
AUTOMATIC RECALL [A-8] to the Attendant in this case.

6. Once a call is answered, it can be processed by the called station like any normal trunk call.

7. If the station is assigned to a STATION HUNTING - CIRCULAR [S-7], STATION HUNTING ­SECRETARIAL [S-8], or STATION HUNTING - TERMINAL [S-9] group, the incoming call will follow
the hunt group station assignment. If the station is in a CALL FORWARDING - BUSY LINE [C-2],
CALL FORWARDING - DON’T ANSWER [C-3], or CALL FORWARDING - ALL CALLS
[C-5] mode, the incoming call is connected to the call forward target station.

8. This feature is normall y used where Direc t-In service is required on a limited basis. The number of station s
thus serviced is eff ectively limited to the num ber of trunks available for DIR E C T-IN TERMINATION.

9. DIRECT-IN TERMINATION and NIGHT CONNECTION - FIXED [N-1] are mutually exclusive.

10. DIT trunks can be programmed to terminate elsewhere in the Night mode.

11. When the system is in the Night mode of operation and the DIRECT-IN TERMINATION (DIT) station
is busy, the call diverts to TAS if provided; otherwise, the call waits on the busy station until it is idle.

12. Only one trunk can be arranged for DIRECT-IN TERMINATION to a particular st atio n line.

13. The DIRECT-IN TERMINATION feature is limit ed to the following trunk types:

a.) CO
b.) automatic-in tie trunk

14. If the a ssigned st ation is bus y when a ca ll arrives, th e call is h eld waiting. The call wai ting tone is not
provided to the DIT station. The calling party hears the ringback tone.

15. The DIT call can terminate to a DO NOT DISTURB - D

General Description

The INTER-PBX COORDINATED STATION NUMBERING PLAN - PRI feature enables the main-satellite
network to coordinate the numb ering plan for stations in the network. This feature allows a station at one switch to
call a sta tion at anoth e r switch by dialing a unique th ree- to seven- d igit number with no ac cess codes or pauses for
dial tone.

This feature can also be arranged to provide a centralized exchange network capability, which channels access to
and from the public network th rough a single NEAX2400 IMX switch in the coordi nated group.

Operating Procedure

This feature is used for the main/s atelli te confi guration and may als o be provi ded with main/tribut ary conf igurati on.
Stations at the main and satellite can dial each other without an intervening dial tone. The dialing plan for an inter­PBX call is the same as for an intra-PBX call. With this arrangement, different initial digits are assigned to stations
on different systems.

I-36 Inter-Office Off-Hook Queuing - PRI

General Description

This feature can be employed in a main-satellite configuration to allow a satellite user to queue for LEAST COST
ROUTING - 3/6-DIGIT - PRI [L-31] at the main location. This feature can also be used when all outgoing ISDN
trunks are concentrated at the main location.

Operating Procedure

Operation at the main location

1. The main location receives dialed digits from the satellite location via ISDN trunk (a TANDEM TIE
TRUNK [T-1]).

2. The main location determines that no ISDN trunks are available and places the call in an available Hold
on Queue.

3. The main location returns service set tone to the satellite caller.

4. The satellite caller remains off-hook, and waits for the call to be completed. (When an ISDN trunk
becomes available, the satellite call er is connected.)

5. If there are no Hold on Queues ava ilable, the main location returns reorder tone to the satellite caller.

6. If the satellite caller goes on-hook (ISDN trunk releases) while in queue, the assigned Hold on Queue is
cleared.

L-31 Least Cost Routing - 3/6-Digit - PRI

L-31 Least Cost Routing - 3/6-Digit - PRI

General Description

This feature allows t he NEAX2400 IMX to be progr ammed to route outgoi ng calls over the mos t economical facil ity
(WATS, FX, DDD). Based on the area code and office code dialed (6-digit analyzing), the system examines the
programming tables and chooses the facilities in the order specified. This service is the only way to access PRI
interface into ISDN.

Operating Procedure

1. Lift the handset; receive dial tone.

2. Dial the access code (usually 9); receive second dial tone.

3. Dial the area code, office code and te lephone number.

4. The system automatically completes the call via the most economical route.

Service Conditions

A step-by-step explanation that, when reviewed in conjunction with the following figure, provides a clearer
understanding of how the NEAX2400 IMX switch accomplishes Least Cost Routing follows:

1. If dialing a toll or local call (NPA-NXX-XXXX or NXX-XXXX), routing begins wit h translation of three ­digit (NPA or NXX) area or office code. In the case of specific numbers, this translation can result in the
immediate selection of the three-digit routing patterns. If the number dialed is an NPA and six-digit
translation is re quired, the NXX code i s verified in th e SCC (XX) or the FX (XX) Tabl e (Note 1 and Note

2). If the NXX is not located in either table, see number 3. There is a maximum of 256 Outgoing Pattern

Routing (OPR) Tables with a maximum of 8 routes for selection.

Note 1: SCC (XX) is the Special Common Carrier NXX Translation Table.
Note 2: FX (XX) is the FX NXX Translation Table.

2. First choice route option in an NPA pattern will most often be a Specialized Common Carrier. If a trunk
is available in this group, fu rther digi t transla tion will be re quired to det ermine whether the ca lled number
is served by the ca rrier. NXX di git tran slation wi ll also b e require d in inst ances where a call is routed ove r
a tie or FX trunk. For these purposes, 256 NXX patter ns are available.

3. In the case of Specialized Common Carriers, associated NXX patterns return either a YES or NO answer
to the switch, indicati ng wheth er the dial ed numbe r is withi n the desig nated ser vice area of the sel ected
SCC. If service is available, the switch seizes the trunk and completes the connection. If the NO answer
is returned, the switch searches for the next available trunk group.

4. Calls routed over FX trunk groups may require outpulsing of prefix digit 1, depending upon the NXX
number dialed. For this purpose, another group of ass ociated NXX patterns can be u sed, operating on the
same YES/NO principle. A YES answer returned to the switch will result in prefix 1 being added
automatically before sending digits to the called central office.

5. When the selected route is an FX trunk gr oup, NXX translati on can be used to either allow or disallow th e
connection. This is accomplished via YES/NO answer from a designated group of NXX patterns, and
enables calls to selected central office areas to be effectively restricted to the most economical routes.

Service Conditions (cont’d)

6. In certain cases, three- and six-digit translation provides sufficient information for identification of the
service area. Up to 256 separate Outgoing Routing Patterns are provided for this.

7. Up to eight trunk routes can be in each Outgoing Routing Pattern.

8. STATION MESSAGE DETAIL RECORDING (SMDR) [S-10] may be used in conjunct ion with LEAST
COST ROUTING - 3/6-DIGIT - PRI. The route selec ted by t he switch wil l be re corded b y the STATION
MESSAGE DETAIL RECORDING (SMDR) [S-10] unit.

9. Tie Lines can be included in route patterns.

10. Application of NXX patterns provides for inclusion of multiple common carriers serving different areas.

11. When a tie trunk requiring an off-net connection to the local central office is included as a route option,
the NEAX2400 IMX can provide a 2.8 second prepause before sending out the selecting signal.

12. Senders (dial pulse or tone) are provided with this feature for dialing.

13. Pre-translation capability minimizes waiting time after dialing. After enough digits are collected to
determine a route, the system starts outpulsing before the station completes dialing the entire called
number.

14. When LEAST COST ROUTING - 3/6-DIGIT - PRI is provided, the Attendant cannot pass dial tone to a
station. The desired number must be dialed by the Attendant.

15. Stati ons having d ifferent Route Restriction Classes, but using the same LEAST COST ROUTING - 3/6­DIGIT - PRI pattern, can be denied acc ess to the last choice trunk route (s) in that pattern. Route Res triction
Classes can be set up so that a station dialing an area code can use WATS, FX, and DDD; or only the
WATS line, if such an arrangement is desired. This is a form of forced Least Cost Routing.

16. NXX patterns can be programmed to restrict all stations in the system from completing calls to specific
NXX numbers over FX trunks.

17. The system includes the ability to detect a dialed DDD number and compare it with a DDD list table to
determine if the call is directed to a facility served by the trunk network. If the dialed number is found in
the DDD list table, a translation is provided to the seven-digit, on-net number (ABC-XXXX) served by
the tie trunk. This allows an expensive public network dialed number to be trapped and automatically be
diverted to an available leased facility. If a Tie Line is not available, the call is routed as dialed.

18. The NEAX2400 IMX is capable of converting a maximum of 24 receiving digits into a required 24-digit
number entirely. An interdigit pause can be inserted whenever necessary. This provides for an extremely
flexible numbering plan for a complex network.

19. CALL-BY-CALL SERVICE SELECTION [C-105] is available on a trunk provisioning basis.
