If requested, this number must be provided to the telephone compa ny.

A plug and jack used to connect this equipment to the premi ses wiring and telephone network must comply with the applicable FCC Part 68 rules and requirements adopted by the ACTA.

The REN is used to determine the number of devices that may be connected to a telephone line. Excessive RENs on a telephone line may result in the devices not ringing in response to an incoming call. In most but not all areas, the sum of RENs should not exceed five (5.0). T o be certain of the number of devices that may be connected to a line, as determined by the total RENs, contact the local telephone company. For products approved afte r July 23, 2001, the REN is part of the product identifier that ha s the format US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point (e.g., 03 is a REN of 0.3).

If your Hx8 Series card causes harm to the telephone network, the telephone company may notify you in advance that temporary discontinuance of service may be required. But if advance notice is not practical, the telephone company will notify you as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it is necessary.

Echo Cancellation

Echo cancellers are normally not required in the Telecom PSTN because geographic delays are acceptable where CPE return loss is maintained within Telepermit limits. However, those privat e networks making use of Voic e over IP technology are r equired to provide echo cancellation for all voice calls. The combined effect of audio / VoIP conversion delay and IP routing delay can cause an echo cancellation time of 64ms to be required.

Chapter 1 Overview

The Hx8 Series cards are versatil e devic es used for connecting your phone network to the PSTN (Publi c Swit ched Telephone Network) world. This is accompli shed through a nalog l ines c onnect ed to the F XO (Forei gn Exchange Office) ports, digital lines connected to the BRI (Basic Rate ISDN) ports, and phone handsets connected to the FXS (Foreign Exchange Station) ports. The Hx8 Series cards allow Asterisk to connect to your phone networ k, creating an office type telephony envir onment. In addition, they can also improve voice quality in environments where software echo cancellation is not sufficient by using hardware echo cancellation on board.

Note: An FXO module cannot be used in combination with a BRI module that is taking timing in TE mode on the same Hx8 Series card. An FXO module can be used in comb ination with a BRI modul e tha t is providing timing in NT mode on the same Hx8 Series card.

The Digium BRI module is compatible with Euro-ISDN. It is capable of serving as a Terminal Equipment (TE) and/or Network Termination (NT) device. When configured as an NT device, it is the source of BRI lines as shown in Figure 1 and Figure 2.

Note: The Hx8 Series cards do not support North American BRI.

There are a variety of applications where the Hx8 Series cards (HA8 or HB8) can prove useful. Examples are provided in the following figures.

Chapter 1: Overview

Echo-Cancellation

Users connecting the ir Hx8 Series cards to the PSTN or other devices are likely to be placing calls that will result, at some point, in an unbalanced 4-wire/2-wire hybrid. The result of this hybrid is the reflection of a nearend echo to the calling party. Elimination of this echo is th e responsibility of echo cancellation.

The Hx8 Series cards, unless otherwise equipped, utilize Asterisk to perform software-based echo cancellation. Asterisk maintains a number of open source ech o can c el lers . The s e open s o urce ech o can ce l le rs provide a moderate level of echo cancellation, but are not capable of dealing with higher levels of, or more advanced, echoes.

Digium recommends that those users concerned about echo cancellation purchase the VPMADT032 hardware echo cancellation module. The VPMADT032 may be combined with both the HA8 and HB8.

The VPMADT032 is desi gned to h andle up to 128m s of e cho cance llati on across all channels and provides a G.168 echo cancellation solution.

Shipment Inspection

The following items are includ ed in shipment of an Hx8 Series card:

 Hx8 Series card (HA8 or HB8)  FXO, FXS, and/or BRI module(s), depending on configuration  4 or 8 Digium BRI RJ11-to-RJ45 cable s for BRI configurations only  Port identification labels

Note: After inspecting the shipment, Digium highly recommends that you register the card for support eligibility. Please refer to Free Installation Support on page 89 for additional information on how to obtain assistance from Digium Technical Support.

Module Identification

The Hx8 Series cards ship with FXO, FXS, and/or BRI modules in place. These are identified by their color. Take a moment to identify which modules were shipped with your card.

 FXO (Foreign Exchange Office) modules are Red  FXS (Foreign Exchange Station) modules are Green  BRI (Basic Rate ISDN) modules are Blue

The Hx8 Series cards may also be combined with Digium’s hardwarebased echo canceller, model VPMADT032. See Figure 5 on page 30 for an example of the HA8 card shown with the echo cancellation module.

Digium, Inc. Page 26

Chapte r 2: C ar d In st a lla tion

Port Identification

Each card consists of eight RJ11 ports located on the bracket. Each RJ11 port correlates to a single FXO or FXS channel, or to a single BRI span. The ports are numbered in sequence from one to eight. The top port is Port 1 and the bottom port is Port 8. See Figure 3 on page 28 for appropriate ident ification of these ports. The port identif ication is the same for all cards in this series.

It is important to identify the type and location of your Hx8 Series modules. You will need this informat ion during the Asterisk configuration.

The ports available for use on the Hx8 Series cards are not continuous. The ports available for use depend upon the type of module used, and the placement of the module on the card. The cards can acce pt 2 quad modules, for a total of 8 ports. If single modules are used, only 2 single modules can occupy the same spac e as a quad module. The single module ports are identifi ed on the card and the ir corresponding RJ11 ports a re identified belo w . Please refer to Figur e 5 on page 30 for an example using a single module, and Figure 6 on page 31 for an example using quad modules.

If a single module is used, the RJ11 port available for use will be the port corresponding to the location of the module on the card. The following ports correspond to the single module ports as shown in Figure 3.

 RJ11 Port 1 is used by Single Module Port 1  RJ11 Port 2 is used by Single Module Port 2  RJ11 Port 5 is used by Single Module Port 5  RJ11 Port 6 is used by Single Module Port 6

Applying a Port Identification Label

Once you have identified the ports of the Hx8 Series card, you should apply a port identification label. This is important in order to ensure that only compatible devices ar e connecte d to the ports o f t he Hx8 Serie s card. It is highly recommended that you apply the label in a clearly visible location near the external port connectors.

Figure 7: Example Port Identification Labels

Note: The port identifica t ion la be ls pack aged with an Hx8 Se ries card may differ from this example.

Card Identification

There are multiple config urations in which an Hx8 Series card may be purchased. Each configuration consists of a combination of single modules, quad modules, or both, and may also include the VPMADT032 echo cancellation modul e. See Table 1 on page 33 for a list of the most common HA8 configurations. See Table 2 on page 35 for a list of the most common HB8 configurations. The lists are not complete, but rather an example of some of the configurations available.

It is easie st to identify your c ard by understanding the naming scheme for each card. The first digit is the maximum port count of the card. The second digit is reserved fo r futur e use. The third digit is the number of BRI ports present on the card. The fourth digit is the number of FXS ports present on the card. The fifth digit is the number of FXO ports present on the card. An “S” in p lace of t he fou rth digi t si gnifie s the use of single FXS modules. An “S” in place of the fif th digit signifies the use of single FXO modules. A “B” at the end signifies the use of a hardware echo cancellation module.

Slot Compatibility

Check the slots on your motherboard to veri fy that you have a slot available w hic h is com p atibl e w ith the Hx8 Seri es card s. To determine which slots you have on your motherboard, identify them by comparing them to those shown in Figure 8.

Slot Number:

0: AGP Pro Slot 1: 64-bit 5.0 volt PCI Slot 2: 64-bit 3.3 volt PCI Slot 3: 32-bit 5.0 volt PCI Slot 4: PCI Express 1-lane (x1) Slot 5: PCI Express 4-lane (x4) Slot 6: PCI Express 8-lane (x8) Slot 7: PCI Express 16-lane (x16) Slot

Figure 8: Motherboard Slots

Digium, Inc. Page 37

Chapte r 2: C ar d In st a lla tion

The HA8 card is a 32-bit 33 MHz card ke ye d for universal 3.3 volt or 5.0 volt operation and works in any PCI 2.2 (or greater) compliant slot. This means that in the motherboard shown in Figur e 8, the HA8 card will fit into Slots 1, 2, or 3 (PCI slots), but cannot fit into any of the other slots.

The HB8 card is keyed f or a PCI Expre ss 1-la ne (x1) sl ot and will work in any PCIe revision 1.0 compliant slot, including lane lengths x4, x8, and x16. This means that in the motherboard shown in Figure 8, the HB8 card will fit into Slots 4, 5, 6, or 7 (PCI Express), but cannot fit into any of the other slots.

Hardware Installat ion

1. Now that you are acquainted with your card, power down your com-

puter , a nd unplug it from its power source.

2. Attach an anti-static strap to your wrist and open the case.

3. Remove the bracket plac e holde r and insert the card into a PCI (HA8)

or PCI Express (HB8) slot. See Figure 9.

Figure 9: Insert the Card

4. If your card has any FXS modules, you will also need to connect the

power cable from your computer’s power supply to the back of the card. Insert a four-pin 12 volt connector (disk drive power supply cable, e.g. hard drive) into the white plastic connector on the rear of the card. See Figure 10.

Digium, Inc. Page 39

Chapte r 2: C ar d In st a lla tion

Figure 10: Connect Power for FXS Modules

Many modern PCs and servers do not have either spa re or any 12V power connectors. If you have FXS modules on your card and your compute r does not have power cables available , then power must be provided to the Hx8 Series card by an alternate means. Digium provides a solution to this issue with the optional PWR2400B (availa ble separately). The PWR2400B card is essentially a PCI bracket assembly that takes power from an external DC power supply and routes it to two 15" power cabl es inside the computer. You must have an available bracket slot to use the PWR2400B (either PCI, PCI Express or AGP).

A strap on the PWR2400B card allows the two power cables to take power from the same DC s upply. The PWR2400B comes with one power supply capable of supporting up to 24 FXS ports, driving heavy loads of up to 5REN per port. If more than 24 FXS ports with heavy loads are connected to the PWR2400B, then a second Digium power supply should

Digium, Inc. Page 40

Chapte r 2: C ar d In st a lla tion

be purchased. The shorti ng strap on the PWR2400B should be removed if a second power supply is used.

The PWR2400B does not connect to any bus inside the computer. It may be used where ver there is an available PC I-s i ze brac ket such as a PCI, PCI Express, or AGP slot.

Note: The PWR2400B is not intended to supply power to any other device, it is intended only to be used with UL Listed Digium analogcapable cards.

5. Replace the cover to your computer.

Electrical Shock

To re duce the risk of injury, damage to the unit or your equipment, do not attempt to apply power to the unit while the case is open. Pe rsonal injury or damage to the unit could occur if the modules are touched while powered is applied.

6. Plug all analog telephone lines to the FXO (red) ports and all analog

phones to the FXS (green) ports as needed using a pa tch panel, punch block, or standard RJ11 telephone cables. Then plug all BRI lines to the BRI (blue) port s using a patc h panel , punch bl ock, or the pr ovided Digium BRI RJ11-t o-RJ45 cables. Refer to the pin assignments starting on page 90.

Caution

This unit must be connected to the Telecommu nications Network in your country using an approved line cord, e.g. : for Australia use only line cords complying with ACA Technical Standard TS008.

Digium, Inc. Page 41

Chapte r 2: C ar d In st a lla tion

Caution

Only connect regulatory equipment (approved for use in your specific country) to the telecommunications network voltage circuit ports.

Chapte r 2: C ar d In st a lla tion

Connecting a Timing Cable

The timing por t allow s u p to three Hx 8 Seri es cards to sha re the sam e sync (timing) source from the BRI line provider, or provide a consistent sync source across multipl e cards. This is a useful feature for fax modes and some voice applications to prevent corruption due to timing slips on the second and third Hx8 Series cards .

To utilize this feature, daisy-chain the P102 connector between each Hx8 Series card using the Digium 3-posi tion, 10-pin timing cable. Enable this feature by using the

timingcable=1 kernel module parameter when the

driver is lo aded:

# modprobe wctdm24xxp timingcable=1

Figure 11: Timing Cable Connection

Digium, Inc. Page 43

Chapte r 2: C ar d In st a lla tion

FXO, FXS, and BRI Connection

The Hx8 Series cards provide eight RJ11 connectors for access to the FXS, FXO, and BRI modules installed in the available slots. Using a standard RJ1 1 telephone cable, an analog telephone line should be plugged into one of the RJ11 connectors associated with an FXO module on the Hx8 Seri es card. Using a standard RJ11 te lephone cable, an an alog phone should be plugged into one of the RJ11 connectors associated with an FXS module on the Hx8 Series card. Using a Digium BRI RJ11-toRJ45 cable, a digital BRI line should be plugged into one of the RJ11 connectors assoc iated with a BRI m odule on t he Hx8 Ser ies ca rd.

Understanding Span and Channel Assignments

In order to properly configure your Hx8 Series card, it is important to understand how spans and channels are assigne d to the card in software. A span is a group of channels that is bundled togeth er in sof t ware . Depending on how an Hx8 Series card is configured , it can have one analog span, four digi tal spans, eight digit al spa ns, or one analo g span a nd four digital spans. The following bulleted lists provide important information regard ing analog and digital spans.

 Analog Span for FXO/FXS

– The analog span will not exist if there are no analog modules

installed.

– The assignment of the analog span alw ays co mes aft er the as sign -

ment of the digital span.

– The analog span always has 8 channels allocated, regardless of the

number of FXO and/or FXS modules that are installed.

– A single implied span exists for all populated and unpopulated ana-

log ports.

– Unpopulated analog ports occupy exactly 1 channel and go into the

analog span.

– As far as the analog span is concerned, BRI ports allocated by a BRI

module are unpopulated ports.

Note: This is extremely important to know when determining the channel assignment of your analog module(s) when a BRI module is installed in the first quad port (non-standard configuration).

Digium, Inc. Page 52

Chapter 3: Configuration

 Digital Spans for BRI

– A digital span will not exist if there are no BRI modules installed. – The assignment of a digital span always comes before the assign-

ment of an analog span.

– Four digital spans are dynamically created for each BRI module on

the card (0, 4, or 8 total spans).

– Digital spans always consist of 2 bchans (i.e. B Channels) and 1

hardhdlc channel (i.e. D Channel). The channels are allocated in that order.

Digium, Inc. Page 53

Chapter 3: Configuration

Driver Configuration

You should ha ve id entifie d the t ype of Hx8 Seri es car d when you rece ived it. If you are not sure, refer to Module Identification on page 26 for assistance.

1. Begin by opening the system.conf file from the

/etc/dahdi directory.

2. Specify the two lett er country c ode for your loa dzone and defaultz one.

This will preload tone zone data and specif y a def ault tone zone for your interfaces.

The following is a typical setup for a telco in the United States:

loadzone = us defaultzone = us

The following is a typical setup for a telco in Spain:

loadzone = es defaultzone = es

Digium, Inc. Page 54

Chapter 3: Configuration

3. If your card has a blue BRI module, you will need to specify span

maps, bchans (i.e. B Channels), a nd hardhdlc chans (D Channels) allocate d to it in the system.conf file.

First, configure the span map for each BRI line. The span map includes defining the span number, timing, line build out, framing, and coding. Configuration details for each of these items i s explained in this section.

span => <Number>,<Timing>,<Line Build Out>,<Framing>,<Coding>[,Yellow][,TE|,NT][,Term]

Number:

This is the port that the BRI line is plugged into. P ort 1 is the furthest span from the PCI connector. The port numbers are noted on the PCI bracket.

Timing:

This determines how timing is handle d by the spans.

0 - Span provides its own timing (master clock) 1 - Receives timing from remote end (slave clock) 2 - Receives secondary backup timing from remote end (slave clock) 3 - Receives tertiary backup timing from remote end (slave clock) 4 - Receives quaternary backup timing from remote end (sla ve clock)

... and so on.

Note: Only one span per card can be defined to tak e timing, and that

Digium, Inc. Page 55

Chapter 3: Configuration

defines timing for the rest of the card’s spans. A setting of 0 should always be used when in NT mode.

Line Build Out:

For most setups the line build out is 0.

0: 0 db (CSU) / 0-133 feet (DSX-1) 1: 133-266 feet (DSX-1) 2: 266-399 feet (DSX-1) 3: 399-533 feet (DSX-1) 4: 533-655 feet (DSX-1) 5: -7.5db (CSU ) 6: -15db (CSU) 7: -22.5db (CSU)

Framing:

BRI utilizes CCS framing.

Coding:

BRI utilizes AMI coding.

Yellow:

The optional yellow flag can be added at the end for transmitting a yellow alarm when no channels are open. For example, a yellow alarm will be transmitted when DAHDI is configured and initialized, but Asterisk is not running. Sending a yellow alarm is useful for the local side to notify the remote side that it is not ready to accept calls, and for determining which direction a communication problem exists

Digium, Inc. Page 56

Chapter 3: Configuration

during troubleshooting. If this setting is unspecifie d and Aster isk is not running, DAHDI will not report an al arm and the remote side will think that the local sid e is ready to acc ep t calls .

TE or NT:

Each of the BRI ports can be set for TE or NT mode independently. Specify TE to act as Terminal Equipment, or NT act as a Network Termination device. The default setting is TE mode.

There is a risk of electrical shock due to lightning when this device is utili zed in TE mode. Take safety pr ecautions when using the card in this man n er.

Term (Termination):

Any BRI port can use 100 ohm termina tion. This s hould be enabl ed if the placement of an Hx8 Series card is the last in a daisy-chain. This is always the case when using PTP mode, and sometimes the case when using PTMP mode. Termination should be disabled only in instances where an Hx8 Series card’s placement is inside of a daisychain. This is never the case when using PTP mode, and sometimes the case when using PTMP mo de. Th e default sett ing is off . Exa mples are provided below.

NT (Term) <----> TE PTP (Term) NT (Term) <----> TE PTMP (Term) NT (Term) <----> TE PTMP (No Term) <----> TE PTMP (Term)

Then you will need to specify the channel definitions for each span.

The channel definition format is:

A list of valid devices are specified in the sample system.conf file. The devices that need to be specified for a BRI module are listed below.

bchan = 1,2,4,5,7,8,10,11 hardhdlc = 3,6,9,12

Digium, Inc. Page 59

Chapter 3: Configuration

The bchan device specifies the beare r channels (B channels). The hardhdlc device specifies the delta channel (D channel).

Note: Unlike Digium’s Digital T1/E1 car ds, the device for the delta

channel must be specified as hardhdlc instead of dchan. The Hx8 Series cards will not function properly if dchan is specified.

The combined configurati on should look like the following:

loadzone = es defaultzone = es

span => 1,1,0,ccs,ami,te,term bchan = 1,2 hardhdlc = 3

span => 2,2,0,ccs,ami,te,term bchan = 4,5 hardhdlc = 6

span => 3,3,0,ccs,ami,te,term bchan = 7,8 hardhdlc = 9

span => 4,4,0,ccs,ami,te,term bchan = 10,11 hardhdlc = 12

If your card has two BRI modules installed, the configuration should

Digium, Inc. Page 60

be specified as the following:

loadzone = es defaultzone = es

span => 1,1,0,ccs,ami,te,term bchan = 1,2 hardhdlc = 3

span => 2,2,0,ccs,ami,te,term bchan = 4,5 hardhdlc = 6

span => 3,3,0,ccs,ami,te,term bchan = 7,8 hardhdlc = 9

span => 4,4,0,ccs,ami,te,term bchan = 10,11 hardhdlc = 12

span => 5,1,0,ccs,ami,te,term bchan = 13,14 hardhdlc = 15

span => 6,2,0,ccs,ami,te,term bchan = 16,17 hardhdlc = 18

span => 7,3,0,ccs,ami,te,term bchan = 19,20

hardhdlc = 21

span => 8,4,0,ccs,ami,te,term bchan = 22,23 hardhdlc = 24

Chapter 3: Configuration

Digium, Inc. Page 62

Chapter 3: Configuration

4. If your card has a red quad FXO module, add the channel definitions

for it to the system.conf file.

The channel definition format is:

A list of valid devices are specified in the sample system.conf file. The device that needs to be specified for an FXO module is listed below.

fxsks =

fxsks uses kewlstart signa lling, which is loopstart signalling with disconnect supervision. For example, an Hx8 Series cards with only a quad FXO module installed would be configur ed as the following:

fxsks = 1-4

fxsks = 1,2,3,4

If two quad FXO modules are installed, the configuration should be specified as the follo wi n g:

fxsks = 1-8

Digium, Inc. Page 63

Chapter 3: Configuration

fxsks = 1,2,3,4,5,6,7,8

Note: The Hx8 Series cards do not support Ground Start signaling.

Note: An FXO module cannot be used in combination with a BRI

module that is taking timing in TE mode on the same Hx8 Series card. An FXO module can be used in comb ination with a BRI modul e tha t is providing timing in NT mode on the same Hx8 Series card.

If a quad FXO module is installed on the first quad slot, and a BRI module is installed on the second quad slot, the configuration should be specified as the following:

loadzone=es defaultzone=es

span => 1,0,0,ccs,ami,nt,term bchan = 1,2 hardhdlc = 3

span => 2,0,0,ccs,ami,nt,term bchan = 4,5 hardhdlc = 6

span => 3,0,0,ccs,ami,nt,term bchan = 7,8 hardhdlc = 9

Digium, Inc. Page 64

Chapter 3: Configuration

span => 4,0,0,ccs,ami,nt,term bchan = 10,11

hardhdlc = 12

fxsks = 13-16

Note: The analog span begins at channel 13 instead of 1 because the assignment of an digita l spans always comes before the assignment of an analog span. Please refer to the Understanding Span and Channel Assignments section f or more details .

If a BRI module is installed on the first quad slot, a nd a quad FXO module is installed on the second quad slot, the configuration should be specified as the following:

loadzone=es defaultzone=es

span => 1,0,0,ccs,ami,nt,term bchan = 1,2 hardhdlc = 3

span => 2,0,0,ccs,ami,nt,term bchan = 4,5 hardhdlc = 6

Digium, Inc. Page 65

Chapter 3: Configuration

span => 3,0,0,ccs,ami,nt,term bchan = 7,8 hardhdlc = 9

6. DAHDI uses modular echo cancellers that are configured per channel.

The echo cancellers are compiled and installed as part of the dahdilinux package. You can specify the echo canceller to be used for each channel. If a hardware echo cancel lation is not installed, the default behavior is for there to be no echo canceller on any channel. So, it is very important that you speci fy one in the system.conf file if you do not have hardware echo cancellers and need echo cancellation. The format is:

echocanceller = <echocanceller name>,<channel(s)>

A list of valid echo cancellers are specified in the sample system.conf file.

The following is a typical setup using software-based echo cancellation:

echocanceller = mg2,1-8

Note: If a hardwa re echo-cance llati on module is inst alled , please refer to Configuring Card Features on page 73 for information on configuring it.

Chapter 4 FXS, FXO, and BRI Explained

Identification

There are multiple config urations in which an Hx8 Series card may be purchased. Each configuration consists of a number of FXS, F XO, and/or BRI modules. These modules are identifie d by their color .

 FXS - Foreign Exchange Station (Green Modules )  FXO - Foreign Exchange Office (Red Modules)  BRI - Basic Rate ISDN (Blue Modules)

This chapter provides a review of the three module types and their uses within your Asterisk server.

Note: Only qualified service personnel should install the card. Users should not attempt to perform thi s function themselves.

FXS Module

The FXS module allows an Hx8 Series card to initiate and send ringing voltage to an FXO device such as an analog telephone. Because of the modular design, you can activate additional ports at any time with more FXS daughter cards.

FXO Module

The FXO module allows an Hx8 Series card to terminate analog telephone lines (POTS) . The FXO module passes all the call features any standard analog telephone line will support. The phone receiving the call

Digiu m, In c . Pa g e 8 2

Chapter 4: FXS, FXO, and BRI Explained

is the last FXO device in the chai n. When it re ceives vo ltage from an FXS device, the phone rings. Because of the modular design, you can activate additional ports at any time with more FXO daughter cards.

BRI Module

The BRI module allows an Hx8 Series card to serve as Terminal Equipment (TE) or as a Network Termination (NT) device. When configured as an NT de vice , it is the source o f BR I lin es. Bec au se of the modular design, you can activate additional ports at any time with more BRI daughter cards.

Using Your Hx8 Series Card

Connect an analog telepho ne line to an FXO port on your Asterisk server to receive voltage from the outside lines.

Connect the BRI line from the NT device to a BRI port on your Asterisk server to se rve as Ter minal Equipment.

Connect an analog phone to an FXS port on your Asterisk server. When the FXO module in your Asterisk Server receive s rin g voltage or

when the BRI module receives a digital message notifying it of an inbound call , Asterisk will generate voltage using the FXS module to ring your analog phone.

Chapter 5 Troubleshooting

This chapter provides frequent ly asked questions a nd possible resolutions as identified by Digium Technical Support. Multiple resources are available t o obtai n mor e infor mation a bout Asterisk and Digium produc ts. Please visit both www.digium.com and www.asterisk. org for more information.

What do the sta tu se s for BRI po rt s in da hd i_t ool in dica te ?

 OK - The card is in-sync with the far end.  YELLOW - The card is seeing the fa r end, but the far end is not se eing

the card.

 RED - The card is not seeing the far end, the circuit is not up, or the

cable is bad.

What type of cable do I ne ed for BR I ?

Digium recommends using the Digiu m BRI RJ11-to-RJ45 cables that are provided with each BRI module. The driver for the Hx8 Series cards will automatically swap the tr ansmit and rece ive pins when going betwee n TE and NT mode. This eliminates the need of using crossover cables. Refer to the pin assignments start ing on page 90.

Digiu m, In c . Pa g e 8 4

Chapter 5: Troubleshooting

Which BRI protocol is used by the BRI module?

The BRI module supports the ETSI standard using CPE- PTP (Point-toPoint), CPE-PTMP (Point-to-Multipoint), and NET- PTP (Point-to-Point).

The FX O module never hangs up the line. Ho w do I s et it to hang-up?

busydetect = yes and busycount = 10 in the chan_dahd i.co nf for

Set your channels. This will cause the line to hang-up by listening for a consecutive number of busy tones. Upon editing chan_dahdi.conf, you will need to restart Aster isk.

I have echo problems on my FXO modules and I've tried the different echo cancellation algorithms in dahdi_config.h, tried tweaking the gains, and still nothing works. What can I do?

Run the fxotune utility with th e -i option (fxotu ne -i 4). It should discover which DAHDI channels are FXO modules and tune them accordingly. Be warned however , it takes a significant amount of time for each modul e to tune. A conservative estimate would be somewhere around 2-3 minutes for each module. You only have to tune the channels once for each line. The fxotune utility will store the calibration settings in /etc/fxotune.conf. You will need to configure your system to run fxotune with the -s flag (fxotune -s) during the Linux boot se quence in order to initialize the previously discovered values which are stored in fxotune.conf. A recommendation is to put ‘f xotune - s’ in y our distrib ution’s startup scripts at some point after the DAHDI module loads and before Asterisk executes.

Note: The digit after the -i option is the DTMF digit that will break dialtone on the line.
