Locate the card slots in the modules that house ISDN BRI cards. Group all SILCs, UILCs, BRSCs, superloops and the MISP that supports them in the same network group to avoid using junctors for dedicated connections.

—End—

The following rules apply when selecting the card slots:

MISPs

•

MISPs are inserted into the Core/Network Module for Large Systems (Multi Group). Refer to the LD 22 printout to identify modules with unused network card slots and to Table 2 "ISDN BRI card location"

(page 16) for the card slots in these modules that can house MISPs.

•

An MISP cannot share network loop addresses with a Superloop Network Card in the Large Systems. The MISP requires two network loop addresses and one network card slot.

•

An MISP supports a maximum of 8 BRSCs and two line cards.

•

An MISP supports a set of 4 SILCs or UILCs when not supporting a BRSC.

•

An MISP can support both BRSCs and SILCs or UILCs at the same time. If it serves one BRSC, an MISP can also support three line cards. If it supports two or more BRSCs, an MISP can also support two line cards.

BRSCs

•

Install one BRSC for each IPE module.

•

With a BRSC conﬁgured, an IPE module can support a maximum of 15 line cards. These can be up to eight UILCs combined with any other seven peripheral cards (including SILCs), or up to 15 SILCs.

SILCs/UILCs

•

The cards are installed in the Core/Network Module or the IPE Module for all system options. Refer to the LD 20 printout to identify modules with unused peripheral card slots.

•

In each module, install a maximum of 15 SILCs, or eight UILCs combined with any other seven peripheral cards (including SILCs). If 15 SILCs are installed, the remaining slots in the module may contain a BRSC, a UILCs, or non-ISDN BRI cards that do not need the - 48 V power supply of the IPE module (this restriction is due to power supply limitations for the module). If eight UILCs are used, you may install any other card which could reside in the IPE module.

connector A on the I/O panel and into the connector labeled A on the MDF, if an SILC or UILC is installed in slot 0 of an IPE module.

Repeat steps 2 through 4 for all cables in that module.

6 Repeat steps 1 through 5 for all modules containing SILCs and/or

UILCs.

Each SILC provides eight four-wire full-duplex ports. These ports are connected to building wiring to form DSLs. These ports are polarity-sensitive. Signal polarity must be maintained along each loop.

Each UILC provides eight two-wire full-duplex ports. These ports are connected to twisted pair building wiring to form DSLs. These DSLs are not polarity-sensitive and, although recommended, it is not necessary to maintain signal polarity along each loop.

Procedure 9 Cross-connecting SILC and/or UILC ports to the building wiring

Step Action

Perform the following steps to cross-connect the SILC and/or UILC ports to the building wiring.

Identify the card type (SILC or UILC) for a connector on the MDF. Refer to the IPE or CE module card location form at the end of this chapter, which shows the card type connected to each I/O panel connector.

Identify transmit and receive pairs on the top of the labeled distribution strip for the card type and module type you are connecting. To identify SILC or UILC ports and their pin numbers, refer to Table 5 "NT8D37 IPE moduleSILC and UILC

pair-terminations for connectors A, E, K, R (12-cable conﬁguration)" (page 33) through Table 11 "Card location form: NT8D37 IPE module (12-cable conﬁguration)" (page 44), which begins on Table 5 "NT8D37 IPE moduleSILC and UILC pair-terminations for connectors A, E, K, R (12-cable conﬁguration)" (page 33).

Note: In Table 5 "NT8D37 IPE moduleSILC and UILC

pair-terminations for connectors A, E, K, R (12-cable conﬁguration)" (page 33) through Table 11 "Card location form: NT8D37 IPE module (12-cable conﬁguration)" (page 44),

the cable pair designated T- T+ is the transmit pair and the pair designated R+ R- is the receive pair of the S/T interface. The cable pair designated T R is the Tx and Rx of the 2B1Q full-duplex U interface.

Identify building wires connected to the bottom of the distribution strip. Refer to the Building Cable Plan, which identiﬁes wires between distribution frames and wall outlets. The Building Cable Plan is developed according to instructions in the "Planning the Site" section in Communication Server 1000M and Meridian 1 : Large System Planning and Engineering (553-3021-120).

Plug in the terminating resistor at the appropriate location in each S/T DSL. See "Engineering Guidelines" in the ISDN Basic Rate

Connecting the ISDN BRI terminals to the DSL

ISDN BRI terminals are connected to DSLs using modular cables up to 10 meters (33 feet) long, with RJ-45 plugs on each end. One end of the cable plugs into the terminal, and the other end plugs into the wall outlet.

Note: All ISDN BRI terminals should comply with CCITT, ANSI, ETSI NET-3, INS NET-64, National ISDN, 1TR6, Numeris VN2, and D70 standards for terminals, and be compatible with the system. For a list of compatible terminals, refer to the ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

Figure 9 "Connect the ISDN BRI terminal to the S/T interface" (page 37)

illustrates a terminal connection to the S/T interface; Figure 10 "Connect the

ISDN BRI network termination (NT1) to the U interface" (page 38) illustrates

a network termination (NT1) connection to the U interface.

Procedure 10 Connecting the ISDN BRI terminals to the DSL

Step Action 1

Plug one end of the modular cable into the ISDN BRI interface connector on the terminal and the other end of the modular cable into the wall outlet.

For an SILC S/T interface terminal with an optional auxiliary power source, plug the power source into the wall outlet, then plug the cable into the power source’s RJ-45 jack. This power source must supply power only to the local ISDN BRI terminal, not back into the DSL through the RJ-45 wall outlet. The power adapter is supplied with the terminal.

3 Program the terminal parameters, such as the Supervisor Position

ID (SPID) and Static Terminal Endpoint Identiﬁer (TEI), as required by the type of terminal. For detailed information pertaining to this procedure, refer to the section "Initialize ISDN BRI terminals", found

ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

Repeat steps 1 and 3 for each terminal to be connected.

—End—

Connecting the terminating resistors

DSLs require that a terminating resistor be connected at the end of each loop. See ISDN Basic Rate Interface Feature Fundamentals (NN43001-580) for engineering rules and locations of terminating resistors. The end of the S/T interface loop has an RJ-45 jack to plug in the telephone cable. Plug the terminating resistor into the RJ-45 jack, and then plug the telephone cable into the terminating resistor.

Note: For every port there is one loop with only one terminating resistor per loop. Each loop can support a maximum of eight telephones.

3. Install clock referencing on the SILC.

4. Install the SILC and/or UILC.

5. Connect the system to the MDF.

6. Cross-connect the MDF (in Terminal Equipment mode). Note: The system, in TIE trunk or CO connectivity, requires a

different wiring conﬁguration than for a line application; the transmit and receive pairs should be reversed, as illustrated in Figure 12

"Connect the network termination to the U interface and to the S/T interface (in TE mode)" (page 43).

Selecting the card slots

Follow the same procedures as described earlier for line applications (refer to Procedure 1 "Selecting the card slots" (page 16)).

Removing the module cover for card installation

Follow the same procedures as described earlier for line applications (refer to Procedure 2 "Remove the module cover for card installation" (page 20)).

Installing the MISP

Follow the same procedures as described for line applications (refer to

Procedure 3 "Installing the MISP" (page 21)).

Installing the clock reference on the SILC

The DSL#0 and DSL#1 on an SILC card can be conﬁgured as the reference clock source, with DSL#0 being assigned for the primary clock reference and DSL#1 being assigned for the secondary clock reference.

The loop number and location of the primary and secondary clock source is conﬁgured in the Digital Data Block LD 73. Refer to the ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

The SILC can recover the network clock from the received data stream using on-chip phase lock loops. The clock frequency that is recovered is

2.56 MHz. The jitter and wander conform to CCITT recommendations.

All of the S/T chips on the SILC could be conﬁgured as Terminal Equipment Slaves (TES), but only the clocks recovered from DSL0 and DSL1 are routed to the back plane connector pins. These clocks are provided as differential pairs on back plane pins. See Table 9 "Clocks as differential

pairs" (page 42).

Automatic clock recovery is done upon the expiration of the free run guard timer. Tracking is restored to the primary reference clock, if deﬁned. If the primary reference clock is disabled, tracking is restored to the secondary reference clock, if deﬁned.

Installing the SILC and the UILC

Follow the same procedures as described earlier for line applications (refer to Procedure 5 "Installing the BRSC, SILC, and UILC" (page 22)).

Connecting the system to the Main Distribution Frame (MDF)

Follow the same procedures as described earlier for line applications (refer to Procedure 8 "Connect the modules to the MDF" (page 24)).

Cross-connecting the Main Distribution Frame (MDF)

The system, in TIE trunk or CO connectivity, requires a different wiring conﬁguration than for a line application; the transmit and receive pairs should be reversed, as illustrated in Figure 12 "Connect the network termination to

the U interface and to the S/T interface (in TE mode)" (page 43).

Introduction

This chapter describes how to prepare ISDN BRI equipment for acceptance testing. It explains how to verify that ISDN BRI cards are enabled and functioning correctly and how to correct any problems before starting the test.

Verifying ISDN BRI operation

After ISDN BRI equipment has been installed and conﬁgured, you can visually inspect ISDN BRI cards to make sure that they are operating correctly by observing their LEDs:

•

Check the red Dis LED located on the MISP faceplate. If the Dis LED on an MISP is lit, check that the MISP is disabled or faulty. If it is extinguished, check that the MISP is enabled and operating. To enable the MISP or to correct a problem, refer to Maintenance (NN43001-718).

•

Check the red LED located on the BRSC faceplate. If the red LED is extinguished, check that the BRSC is enabled and operating correctly. If the red LED is lit, check that the BRSC is manually disabled or faulty. To enable a BRSC or to correct a problem, refer to ISDN Basic Rate Interface Maintenance (NN43001-718).

•

Check the red LED located on the SILC and UILC faceplates. If the red LED is extinguished, check that the SILC or UILC is enabled and operating correctly. If the red LED is lit, check that the SILC or UILC is manually disabled or faulty. To enable an SILC or a UILC or to

correct a problem, refer to ISDN Basic Rate Interface Maintenance (NN43001-718).

If all indicator LEDs on ISDN BRI equipment are extinguished (with the exception of the CC LED on an MISP), the equipment is functional and you can set up the terminals for this test.

Setting up ISDN BRI test terminals and trunks

Set up ISDN BRI terminals

To conduct acceptance testing for ISDN BRI terminals, you must have a setup that can verify basic ISDN BRI functions and features. Figure 13

"ISDN BRI acceptance testing setup for terminals" (page 49) shows an

example of the ISDN BRI terminal arrangement. You may wish to establish a different test setup, which can be determined by the type of terminals implemented in a speciﬁc customer conﬁguration. You may want to setup communication between ISDN BRI and non-ISDN terminals.

Refer to the ISDN Basic Rate Interface Installation and Commissioning (NN43001-318) for ISDN BRI terminal installation instructions.

Procedure 13 Performing acceptance testing

Step Action

To perform acceptance testing of ISDN BRI terminals:

Select three DSLs, two connected to different SILCs and one to a UILC.

Equip each SILC DSL with two voice, one circuit-switched data, and one low speed packet data ISDN BRI terminals.

Note: Packet data testing can be conducted only if an external packet handler or an Meridian Packet Handler (MPH) is installed as part of the customer conﬁguration, and is supported by the system (like the external DPN-100 packet handler). If packet handler is not part of the conﬁguration, do not equip the DSLs with packet data terminals and skip all the packet data tests speciﬁed in this chapter.

Equip the UILC DSL with a network terminator (NT1) and connect the two voice and one circuit-switched data ISDN BRI terminal to the S/T interface on the NT1.

Conﬁgure the DSLs to support these ISDN BRI terminals and initialize the terminals as described in the "Initialize ISDN BRI terminals" section of the ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

is connected to a Network Termination (NT1) device, which is physically located on the same premises as the system. The NT1 device connects to the Local Exchange that supports Numeris VN2, 1TR6 or D70 protocol through a U interface. The distance limitation of the NT1 from the Local Exchange depends on the distance supported by the Local Exchange.

To achieve system clock synchronization, conﬁgure the system as a slave to the local exchange. Derive the clock source from either the ISDN BRI Local Exchange connection or the other ISDN BRI/PRI/DTI local exchange connections, if available.

After you complete the acceptance testing setup, proceed with the test described in "Testing ISDN BRI functions" (page 87).

•

Any other LED behavior indicates a defective MISP circuit card. Note: The Flash ROM can become corrupted if loss of power

occurs during programming of the Flash ROM. If this occurs, the Flash ROM automatically re-initializes when the MISP is installed and powered up. The automatic re-initialization delays the completion of the self-test, and it takes ﬁve minutes for the LED to ﬂash three times.

Installing the clock controller on the MISP (for trunking applications)

A clock controller is only required for ISDN BRI trunk applications. The system supports a single active clock controller. This clock controller can support a primary and a secondary reference clock. These reference clock sources are derived from BRI spans or DSLs (DSL 0 and/or DSL 1).

A clock controller is required in every cabinet or MG 1000S that contains a digital trunk.

The line cards associated with BRI DSLs used as clock references are installed in the Small System main cabinet or Media Gateway.

Use the following guidelines when installing the clock controller on the MISP:

•

If the primary reference clock source comes from a PRI or DTI, then the clock controller is a daughterboard on the DTI/PRI card.

Release 5.0 20 June 2007

Page 61

Installation procedures 61

•

If the primary reference clock is derived from a BRI DSL, then the CC daughterboard is on the MISP associated with that line card. DSL0 of that line card is used to generate the reference clock.

•

To use a DTI/PRI as a secondary clock source reference, the clock controller daughterboard must reside on a DTI, PRI, or MISP. The clock is extracted from the target DTI/PRI span and routed to the clock controller over the back plane.

•

To use a BRI DSL as a secondary clock source reference, the clock controller daughterboard must reside on a DTI/PRI or an MISP. The clock is extracted from DSL1 of the source line card and routed over the backplane to the CC.

Procedure 17 Installing the SILCs and UILCs

Note: The cable pair designated T R is a 2B1Q full-duplex U interface.

Cross-connecting the DSLs Each SILC provides eight four-wire,

full-duplex ports. These ports connect to building wiring facilities to form DSLs. Since the DSLs are polarity-sensitive, maintain signal polarity along each loop as shown in Figure 26 "Cross-connecting a SILC port to the ofﬁce

wiring" (page 73) on Figure 26 "Cross-connecting a SILC port to the ofﬁce wiring" (page 73).

Each UILC provides eight two-wire full-duplex ports. These ports connect to twisted pair building wiring facilities to form DSLs as shown in Figure 27

"Cross-connecting a UILC port to the ofﬁce wiring" (page 74) on Figure 27 "Cross-connecting a UILC port to the ofﬁce wiring" (page 74). The DSLs

are not polarity-sensitive, and it is not necessary to maintain signal polarity along each loop.

Procedure 21 Cross-connecting the DSLs at the cross-connect terminal

Step Action

To cross-connect SILC and/or UILC ports to the building wiring:

1 2

Identify the card type (SILC or UILC) at the cross-connect terminal. Identify the transmit and receive connections for the SILC and

the TIP and RING connections for the UILC from the label of the distribution strip.

Refer to Table 19 "M5317TDX terminal error codes" (page 81) to identify ports and their connections for a SILC or UILC.

Installation procedures 75

Connecting the ISDN BRI terminals ISDN BRI terminals are connected to DSLs using modular cables not longer than 10 m (33 ft) with RJ-45 type plugs on each end. One end of the cable is plugged into the terminal, and the other end is plugged into the telephone outlet.

All terminals must be compatible with the system and comply with one of the following protocols for ISDN BRI terminals:

•

ETSI NET-3

•

INS NET-64

•

NUMERIS

• ANSI standards Contact your Nortel Networks representative for the latest list of compatible

terminals. To connect 1TR6 terminals, an ETSI NET-3 to 1TR6 protocol converter

is required. A terminal adapter (the So-Adapter) has been speciﬁcally designed to interface with the ISDN BRI DSL and the 1TR6 terminals. Its main function is to convert 1TR6 protocol, sent from the 1TR6 terminal into the ETSI NET-3 protocol required for ISDN BRI.

S/T interface speciﬁcation

The S/T interface uses an 8-conductor modular cable terminated with an 8-pin RJ-45 type plug. An 8-pin RJ-45 type jack located on the terminal connects the terminal to the DSL using this modular cable.

Table 17 "S/T interface connector speciﬁcation" (page 75) shows the

connector pin assignment for the jack and the plug. It also shows the signal names for each interface pin at the SILC and at the terminal.

Note 1: Power Source 1 (PS1): Up to 2 Watts of power is supplied by the SILC to the terminals on the DSL. This power is simplexed over the TX and RX pairs provided by -48 V (-40 V for Europe) supply on the SILC. The RX pair is positive with respect to the TX pair.

Note 2: Power Sink 2 (PS2) provides an optional means of powering the terminal from a common supply in the wiring closet.

Note 3: Power Source 3 (PS3) provides the power from the terminal to the NT1 if the NT1 does not have a local power source.

U interface speciﬁcation

The U interface uses a 2-conductor, twisted pair cable terminated with an RJ-45 type jack. An RJ-45 type jack on the NT1 device connects the terminal to the DSL using this twisted pair cable.

The connector pin assignments for the jack and the plug are shown in Table

18 "U interface connector speciﬁcation" (page 76). The table also shows

signal names for each interface pin at the UILC and at the terminal.

Cross-connecting DSLs Each SILC provides eight four-wire, full-duplex ports. These ports connect to the trunk wiring facilities (typically cabling or wiring from outside the building) to form DSLs. Since the DSLs are polarity-sensitive, maintain signal polarity along each loop as shown in Figure 30 "Cross-connecting an SILC port" (page 84) on Figure 30

"Cross-connecting an SILC port" (page 84).

Each UILC provides eight two-wire full-duplex ports. These ports connect to twisted pair trunk wiring facilities to form DSLs, as shown in

Figure 31 "Cross-connecting a UILC port" (page 85). The DSLs are not

Place an outgoing call by dialing an idle ISDN BRI or a non-ISDN BRI terminal.

5 6

Complete this outgoing call and hang up. Have another ISDN BRI or non-ISDN BRI terminal call while the ﬁrst

call is still on hold.

Answer the incoming call and place it on hold.

8 Retrieve the call ﬁrst held. 9

10 11

Complete the call and hang up.

Retrieve the second call on hold. Complete the call and hang up.

—End—

This test can be repeated for terminals connected to the same DSL, different DSLs on the same card, different DSLs on cards associated with different MISPs/BSRCs, and between ISDN BRI and non-ISDN BRI terminals.

Call Waiting

Call Waiting informs an ISDN BRI terminal user engaged in an active call that a call is waiting to be answered. A call setup message is sent to a DSL when both B-channels are busy and an incoming call is in progress. This causes a warning tone to the terminal speaker. To accept the new call, the user must place the currently active call on hold or release the call.

Call Waiting is activated only if Hunting is not enabled or fails to handle the incoming call. The incoming call may originate from an ISDN BRI or a non-ISDN BRI terminal.

Note: The following test requires that the terminal receiving the second (call waiting) call has multiple DN appearances. Otherwise, this test will fail.

Procedure 28 Perform a Call Waiting test

Step Action 1

Set the FEAT parameter to HTD to disable Hunting. Use LD 27 to specify this parameter when conﬁguring the Terminal Service Proﬁle (TSP) for the two voice ISDN BRI DNs on one of the DSLs.

See "TSP conﬁguration procedures" in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

From an ISDN BRI terminal with disabled hunting, dial another ISDN BRI terminal and establish an active call connection.

From the second ISDN BRI terminal with disabled hunting, dial another ISDN BRI terminal and establish another active call connection. Both B-channels on the DSL are now busy.

Note: Only two ISDN BRI terminals may be on the same DSL to allow them to connect. The other two ISDN BRIs are on a different DSL.

Place an incoming call to one of the busy ISDN BRI terminals with disabled hunting.

Observe the called ISDN BRI terminal. The ringing or warning tone should sound, indicating that a call is waiting.

6 7

Place the active call on hold and answer the call that is waiting. Complete the incoming call and hang up.

8 Retrieve the call on hold. 9

Complete the call and hang up.

Call Forward No Answer

Call Forward No Answer and Second Level Forward No Answer forwards an unanswered call to a Call Forward No Answer Directory Number (DN) after a predetermined number of rings. This feature is enabled at the TSP level when deﬁning the ISDN BRI DN. Both the external and internal Call Forward No Answer features are conﬁgured at the DSL level using LD 27. The call can be speciﬁed to be forwarded to the attendant, to an assigned hunting DN, or to a ﬂexible Call Forward No Answer DN by using LD 15.

When a call originated by an ISDN BRI terminal is forwarded to a predetermined DN speciﬁed in LD 15, the display on that ISDN BRI terminal is not updated to indicate a call modiﬁcation.

Procedure 29 Performing a Call Forward No Answer test

Step Action

Voice calls 91

Set the FEAT parameter to FNA and SFA to enable Call Forward No Answer and Second Level Forward No Answer. (SFA is needed only to test two levels of Call Forward No Answer.) Use LD 27 to specify these parameters when conﬁguring the TSP for one of the two voice ISDN BRI terminal DNs. See "TSP conﬁguration procedures" in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

Specify the attendant as the forwarding DN using LD 15. At the FNAL prompt, enter ATT to specify forward to attendant. Refer to LD 15 in the Software Input Output Administration (NN43001-611) for more details.

From an ISDN BRI terminal, place a call to the ISDN BRI terminal with the enabled Call Forward No Answer feature and the speciﬁed call forward to attendant.

Do not answer the call. After a predetermined number of rings, the call is forwarded to the attendant. The display on the call-originating ISDN BRI terminal will not be updated to indicate that the call has been modiﬁed and forwarded to the attendant.

Verify the call was forwarded to the attendant by answering the call at the attendant console. The attendant console will display the call-originating identiﬁcation number and the notiﬁcation of call redirection.

6 Hang up at the call-originating ISDN BRI terminal to release the

call connection.

Calling Line Identiﬁcation Presentation and Restriction

Calling Line Identiﬁcation Presentation and Restriction allows a calling party number (Calling Line Identiﬁcation) to be shown on a called party ISDN BRI terminal display. Use LD 27 to specify this feature when conﬁguring the TSP for the ISDN BRI terminal DN. See "TSP conﬁguration procedures" in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

This feature gives the calling and the called parties the option of displaying the calling line identiﬁcation as follows:

•

The called party ISDN BRI terminal must have the calling line presentation (CLIP) parameter value set to YES to accept the calling line identiﬁcation and show it on its display.

•

If there is an option on the ISDN BRI terminal that enables the calling party to allow or restrict the presentation of the calling line ID on a per call basis, select the option to allow presentation. This option on the terminal overrides the PRES parameter values entered in the TSP data block when conﬁguring the TSP. This depends on the telephone conﬁguration default. See "TSP conﬁguration procedures" in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

Procedure 30 Perform a Calling Line Identiﬁcation Presentation test

Step Action 1

Conﬁgure both the calling and the called party ISDN BRI terminal DN with CLIP = YES and PRES = YES.

Place a call from one terminal to the other and observe the display on the called party ISDN BRI terminal. The Calling Line Identiﬁcation should be displayed during ringing and for the duration of the call.

3 4

Release the call at the called or calling party terminal. Set PRES = NO in the TSP data block for the calling party ISDN BRI

terminal. If the calling party ISDN BRI terminal has an option on the set to allow or restrict the presentation of the calling party number, select the option to allow presentation and place a call to another ISDN BRI terminal.

Observe the called party ISDN BRI terminal display. You should see the number being displayed.

Release the call connection.

Procedure 31 Perform an ISDN BRI Conference test

Step Action

The same procedures can be used to test ISDN BRI NI-1 or ETSI Conference.

In the DSL conﬁguration in LD 27, set PRID = 6 to select the National ISDN-1 protocol, or set PRID = 2 for the ETSI protocol.

In the TSP conﬁguration in LD 27, deﬁne conference under FEATID: FEATID aaa mmm <nnn>, where aaa = A03 (3-party conference) or A06 (6-party conference)

mmm = feature activation ID (0 - 127) nnn = feature indication ID (0 - 127) (If nnn is not entered, it is assumed to be the same as mmm)

Select National ISDN-1 or ETSI protocol on the ISDN BRI terminal if signaling type/protocol is conﬁgurable.

On the ISDN BRI terminal, conﬁgure Conference. This procedure largely depends on the implementation of feature key management on individual terminals. In general:

a. The terminal provides Conference as a selectable feature to be

programmed on a hard/soft key. For example, on a soft key on an M5317TDX, select FA to be FCC; on a hard key on an M5209TDcp, select CONF.

b. The Conference key number selected on the terminal must

correspond to the feature activation ID entered for the TSP in LD 27.

Conﬁgure at least two DN appearances on the ISDN BRI terminal. On some ISDN BRI terminals, the second DN appearance allows the user to initiate the second call.

6 7

Place an outgoing call from the ISDN BRI terminal. After the call is established, press the Conference key. The ﬁrst call

is put on hold automatically; a second key is lit to allow the user to place the second call.

Place another outgoing call from the second key.

Step Action 1

In the DSL conﬁguration in LD 27, set PRID = 6 to select the National ISDN-1 protocol, or PRID = 2 for ETSI protocol.

In the TSP conﬁguration in LD 27, deﬁne conference under FEATID: FEATID aaa mmm <nnn>, where aaa = A03 (3-party conference) or A06 (6-party conference)

mmm = feature activation ID (0 - 127) nnn = feature indication ID (0 - 127) (If nnn is not entered, it is assumed to be the same as mmm)

3 On the ISDN BRI terminal, if the signaling type/protocol is

conﬁgurable, then select National ISDN-1or ETSI protocol.

On the ISDN BRI terminal, conﬁgure Conference. This procedure largely depends on the implementation of feature key management on individual terminals. In general:

a. The terminal provides Conference as a selectable feature to be

programmed on a hard/soft key. For example, on a soft key on an M5317TDX, select FA to be FCC; on a hard key on an M5209TDcp, select CONF.

b. The Conference key number selected on the terminal must

correspond to the feature activation ID entered for the TSP in LD 27.

Conﬁgure at least two DN appearances on the ISDN BRI terminals. On some ISDN BRI terminals, the second DN appearance is used to allow the user to initiate the second call.

Place an outgoing call from the ISDN BRI terminal.

ISDN BRI Special Hunting

ISDN BRI Special Hunting allows a call encountering a destination that has a call in progress to be automatically routed to a different destination in a hunt chain. Hunting continues along a predetermined sequence of DNs in a hunting group until an idle ISDN BRI or non-ISDN BRI terminal DN is found or until the maximum number of hunt steps is exhausted. Use LD 27 to deﬁne the hunting DNs in the DSL. See "DSL conﬁguration procedures" in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

—End—

Special hunting for ISDN BRI supports calls terminating at an ISDN BRI terminal. This feature is activated when a call terminating at a DSL encounters a busy condition and if hunting is enabled. Internal and external hunt DNs can be speciﬁed when conﬁguring the DSL.

A busy condition occurs:

•

if the maximum number of calls on a DSL exceeds the speciﬁed limit of calls on a DSL including active, calls held, calls waiting, and calls in progression (as conﬁgured on LD 27), or

•

if the total number of calls including active, calls held, calls waiting, and calls in progress exceeds the number of channels conﬁgured to handle the incoming call type.

If the call limit on a DSL is not exceeded, an incoming call is presented to the DSL interface as a call waiting call. If Hunting is enabled, the call will be hunted.

Use LD 27 to enable or disable Hunting when conﬁguring the TSP for the ISDN BRI terminal DN. See "TSP conﬁguration procedures" in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

Procedure 33 Perform a hunting test

Step Action 1

Set the FEAT parameter to HTA to enable hunting for two voice ISDN BRI terminals. Use LD 27 to specify this parameter when conﬁguring the TSP. See "TSP conﬁguration procedures" in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

Use LD 27 to specify the HUNT parameter DNs when conﬁguring the DSL. These hunt parameter DNs specify the members of a hunting chain. See "DSL conﬁguration procedures" in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

Place two calls, one for each voice ISDN BRI terminal, on a DSL to create a DSL busy condition.

Place a voice call to one of the busy ISDN BRI terminals with hunting enabled. Since the channel type required to handle the incoming call type is busy, hunting is automatically invoked to ﬁnd an idle DN in the hunting chain.

The following can occur:

•

If the call ﬁnds an idle voice ISDN BRI or non-ISDN BRI terminal, it will ring that terminal.

•

If hunting is not successful: — the originating party receives a busy tone if the total number

of calls on the DSL (as conﬁgured on LD 27) exceeds the maximum number of calls allowed, or

•

5 Place the active call on hold and answer the incoming call that is

waiting.

Complete the incoming call and hang up.

7 Retrieve the call on hold. 8

Release the call connection.

ISDN Basic Rate Interface Installation and Commissioning

— the call is placed in call waiting if the maximum number of

calls on the DSL is below the speciﬁed limit.

If the call is placed in call waiting, observe the called ISDN BRI terminal. You should get a visual indication of the next DN and receive an audible tone.

ISDN BRI National ISDN-1 Call Forward All Calls

National ISDN-1 Call Forward All Calls enables a user of an ISDN BRI terminal to have calls redirected from the user’s DN to another DN. Calls are redirected regardless of the busy or idle status of the interface to the user. Call Forward is assigned on the basis of the directory number and call type (that is, the user may have voice calls forwarded, while data calls terminate normally).

Procedure 34 Perform an ISDN BRI NI-1 Call Forward All Calls test

Step Action

The following is to test the forwarding of a voice call from an ISDN BRI M5317 set.

ISDN BRI ETSI Call Forwarding Unconditional

The ISDN BRI ETSI Call Forwarding Unconditional (CFU) supplementary service allows an incoming call to an ISDN BRI terminal to be forwarded to a predetermined destination, within or outside the system. The call is forwarded whether the user is busy or idle.

An ISDN BRI user can assign the same address or a different address for voice or data calls being forwarded. Calls can also be forwarded to an ISDN BRI terminal or a non-ISDN BRI terminal. When the CFU feature is activated, outgoing calls can still be made from the ISDN BRI terminal.

The ETSI supplementary service provides Call Forwarding capabilities to all users on the access (that is, all the DNs deﬁned under a Digital Subscriber Loop (DSL), or an individual user (that is, a DN).

Procedure 35 Perform an ISDN BRI ETSI Call Forwarding Unconditional test

Step Action

The following test is for forwarding a voice call from an ISDN BRI M5317 set.

1 Set up ISDN BRI ETSI Call Forwarding Unconditional in Overlay 27

(refer to the "Conﬁguring ISDN BRI features" chapter in ISDN Basic Rate Interface Feature Fundamentals (NN43001-580)).

(enter voice call forward).

On the ISDN BRI terminal, conﬁgure ISDN BRI ETSI Call Forward Unconditional.

Conﬁgure two DN appearances on the ISDN BRI terminal (use the ﬁrst DN to forward a call, and the second DN to place a call to test the call forward). On some ISDN BRI terminals, the second DN appearance allows the user to initiate the second call.

Activate ISDN BRI ETSI Call Forwarding Unconditional on the ISDN BRI terminal, for the ﬁrst DN:

a. Press the Forward key. b. Dial the number where calls are to be forwarded. c. Press the Forward key.

Note: Call Forward Reminder Tone should be provided to the ISDN BRI terminal.

To cancel ISDN BRI ETSI Call Forwarding Unconditional: a. Press the Forward or the Cancel key.

Circuit-switched data calls

A circuit-switched data call can be established between two data terminals over a B-channel. The call is set up the same wayas a voice call. Dial a call using the ISDN BRI terminal key pad or keyboard, depending on the type of ISDN BRI terminal used. After the connection is established and the called ISDN BRI terminal sends an acknowledgment that it is ready to receive data, the call-originating ISDN BRI terminal can start transmitting user data.

If the call-originating ISDN BRI terminal requests access to data stored in another ISDN BRI or non-ISDN BRI terminal, it may have to provide a password to be able to access that data.

Note: Follow the instructions in the ISDN BRI terminal user manual for a detailed description of how to set up a call connection and how to transmit and receive data.

In general, data terminals are divided into the following categories:

•

intelligent terminals, such as personal computers

•

dumb terminals such as video display terminals

Repeat this test on several terminals, including both intelligent and dumb terminals as needed.

Procedure 36 Perform a circuit-switched data call test

Step Action 1

From an ISDN BRI data terminal, dial another ISDN BRI data terminal and establish an active call connection.

After receiving an acknowledgment that the other terminal is ready, begin transmitting data.

Verify that the transmitted data has been received successfully by checking transmitted information for accuracy. Read the information on the screen or print it on the local printer.

Packet data transmission

A packet data call can be established between two data terminals over a B-channel or a D-channel.

B-channel packet data terminals communicate with the packet handler at 64 kbps over dedicated B-channels. The packet handler may be an external packet handler, the DPN-100, or the integrated MPH. The packet handlers processes and distributes the data to local terminals for local calls or over the packet data network for remote calls.

D-channel packet data terminals communicate at a baud rate of up to 9.6 kbps. The packet data is multiplexed onto a 64 kbps BD that is linked with the external packet handler through a dedicated ISDN PRI B-channel, or, in the case of the MPH, through a dedicated connection.

Note: To perform packet data transmission veriﬁcation, the system must be connected to a DPN-100, or conﬁgured with MPH. Also, packet data transmission functions must be selected when conﬁguring the B-channel and D-channel transmission characteristics. Use LD 27 to specify the packet data transmission functions. See "MISP conﬁguration procedures" in

(NN43001-580).

ISDN Basic Rate Interface Feature Fundamentals

In addition to conﬁguring the MISP and the DSL in LD 27, ensure the following:

•

the ISDN PRI loop carrying packet data was conﬁgured in LD 17

• the packet handler route was speciﬁed in LD 16

•

an ISDN PRI channel for the packet handler route was conﬁgured using LD 14

See ISDN Basic Rate Interface Feature Fundamentals (NN43001-580) for a detailed description of how to conﬁgure relevant ISDN BRI packet data transmission parameters in LD 17, LD 16, and LD 14.
