B410P is a half-length universal 3.3V and 5.0V 32-bit PCI 2.2 card, that supports four BRI S/T interfaces.
Every port can be independently configured in TE or NT mode. The card can also supply power to ISDN phones via upcoming additional PWR400M module.

The card has onboard hardware echo cancellation performing 64ms or 512 taps for each of the eight channels.

Hardware Installation

Software Installation:

Card configuration:

After successful installation of zaptel and Asterisk, we have to configured the B410P card.

For the auto-configuration and loading the driver, the script '/etc/init.d/misdn-init' will be used.

Usage: /usr/sbin/misdn-init start|stop|restart|config|scan|help
--start scan /etc/misdn-init.conf and load the mISDN drivers
--stop unload the mISDN drivers
--restart see stop, then start
--config scan your PCI bus for mISDN compatible hardware and generate
a /etc/misdn-init.conf
--scan scan your PCI bus for mISDN compatible hardware and print
the results to the console
--help print the usage info

Let's begin.
1) Execute:
# /etc/init.d/misdn-init scan

2) To save the configuration run:
# /etc/init.d/misdn-init config

3) (optional) Edit '/etc/misdn-init.conf', if you need to make changes in configuration.

Example:
/etc/misdn-init.conf

card=1,0x4
nt_ptp=1,2
te_ptp=3,4
poll=128
dsp_options=0
debug=0

Some explanation on the available options:
Card Settings
-------------
card=<number>,<type>[,<option>...]
- <number> count your cards beginning with 1
- <type> either 0x1,0x4 or 0x8 for your hfcmulti hardware,
or the name of your card driver module.
- <option> ulaw - uLaw (instead of aLaw)
dtmf - enable DTMF detection on all B-channels
pcm_slave - set PCM bus into slave mode
If you have a set of cards, all wired via PCM. Set
all cards into pcm_slave mode and leave one out.
The left card will automatically be Master.
ignore_pcm_frameclock - this can be set in conjunction with
pcm_slave. If this card has a
PCI Bus Position before the Position
of the Master, then this port cannot
yet receive a frameclock, so it must
ignore the pcm frameclock.

rxclock - use clocking for pcm from ST Port
crystalclock - use clocking for pcm from PLL (genrated on board)
watchdog - This dual E1 Board has a Watchdog for
transparent mode
Example:
card=1,0x4

Port settings
<port_type>=<port_number>[,<port_number>...]
- <port_type> te_ptp - TE-Mode, PTP
te_ptmp - TE-Mode, PTMP
te_capi_ptp - TE-Mode (capi), PTP
te_capi_ptmp - TE-Mode (capi), PTMP
nt_ptp - NT-Mode, PTP
nt_ptmp - NT-Mode, PTMP
- <port_number> port that should be considered

Example:
nt_ptp=1,2
te_ptp=3,4

Port Options
option=<port_number>,<option>[,<option>...]
- <option> master_clock - use master clock for this S/T interface
(only once per chip, only for HFC 8/4)
optical - optical (only HFC-E1)
los - report LOS (only HFC-E1)
ais - report AIS (only HFC-E1)
slip - report SLIP (only HFC-E1)
nocrc4 - turn off crc4 mode use double frame instead
(only HFC-E1)

Example:
option=1,master_clock
option=2,ais,nocrc4
option=3,optical,los,ais,slip

General Options for your hfcmulti hardware
poll=<number>
Only one poll value must be given for all cards.
Give the number of samples for each fifo process.
By default 128 is used. Decrease to reduce delay, increase to
reduce cpu load. If unsure, don't mess with it!!!
Valid is 32, 64, 128, 256.

dsp_poll=<number>
This is the poll option which is used by mISDN_dsp, this might
differ from the one given by poll= for the hfc based cards, since
they can only use multiples of 32, the dsp_poll is dependant on
the kernel timer setting which can be found in the CPU section
in the kernel config. Defaults are there either 100Hz, 250Hz
or 1000Hz. If your setting is either 1000 or 250 it is compatible
with the poll option for the hfc chips, if you have 100 it is
different and you need here a multiple of 80.
The default is to have no dsp_poll option, then the dsp itself
finds out which option is the best to use by itself

pcm=<number>
Give the id of the PCM bus. All PCM busses with the same ID
are expected to be connected and have equal slots.
Only one chip of the PCM bus must be master, the others slave.

debug=<number>
Enable debugging (see hfc_multi.h for debug options).



dsp_options=<number>
set this to 2 and you'll have software bridging instead of
hardware bridging.

dtmftreshold=<milliseconds>
Here you can tune the sensitivity of the dtmf tone recognizer.

Example:
poll=128
#dsp_poll=128
#dtmftreshold=100
debug=0

4) After all required steps are completed, it's time to load the driver:

/etc/init.d/misdn-init start

5) (optional) How to verify that the driver is loaded and the card is found?

To check if the driver is loaded, just execute:
# lsmod | grep hfcmulti

for the card:

# dmesg | grep Digium

- Asterisk configuration

The configure the Asterisk to operate with the installed and configured B410P card, we have to edit '/etc/asterisk/misdn.conf':

Let's took a look how to configure the card to work with Asterisk. The configuration is done in the /etc/asterisk/misdn.conf:

First you have some general settings and if you need you can turn the debug option on.


The configuration used for the tutorial is listed below:

/etc/asterisk/misdn.conf



Besides [general] and [default] sections, there are two additional sections: [panasonic] and [isdn]. These sections are the Groups used that your dialing through the dialplan.

In example:
101,1,Dial(mISDN/g:panasonic/101)
_0X,1,Dial(mISDN/g:isdn/${EXTEN})


In this tutorial port 1 is set in NT mode and is connected to Panasonic PBX. Port 4 is set as TE mode and is connected to the ISDN line. All incoming calls to these ports jumps to the specific context (context=<value>).

1. When executing /etc/init.d/misdn-init start, you get similar error:

As you can see the type and protocol are empty:
