Number of BRI ports
The Patton Smartnode SN-DTA/1BIS2V/EUI allows you to connect 1 ISDN line , so you have 1 NT port available. This is
also called a BRI port .
The 1BIS2V naming convention means 1 ISDN NT port with 2 voice channels .
Number of channels
By default, you have 2 conversation channels , so you can to conduct up to 2 simultaneous conversations .
Network connection
Your Patton SmartNode DTA has a network connection with a 10/100 Mbps speed and of course also with a
quality of service (QoS) functionality.
Reliability and stability
We have noticed from experience that Patton SmartNode offers very reliable and stable gateways and routers on the market.
After several implementations, we can confidently inform you that Patton SmartNode is still unbeaten in this
domain.
Call quality
An annoying problem that can occur during a call is echo or noise. For both issues, precautions have been taken so that
you take advantage of echo cancellation and a configurable jitter buffer.
NT or TE?
In ISDN, people like to use specific terminology that makes ISDN somewhat complex at first glance. But it is not
too bad, as long as you don't dive into the protocol.
You often hear about NT, TE, and s0 buses. It's just that ISDN has two different ports. A port of network termination (NT) and a
of terminal equipment (TE) . You usually get the NT port from your ISDN line provider, the TE port is on your
ISDN phone. And you must always connect a TE port to an NT port and vice versa. So, in simple terms, if you want to
connect to an ISDN line from your provider (for example Belgacom or KPN), you want to do it with a TE port. If you want to
to connect an ISDN phone, you can provide an NT port for this purpose. If you want to connect a telephone PBX
classic, you can pretend to be an ISDN phone and connect to an S0 bus with a TE port (because an S0 bus is a
different nomenclature from NT).
Multimode?
You often hear the word S0-bus come up, pay particular attention to the 'bus' part. With ISDN, it is also possible to do
handle an incoming call by various devices (for example, various PBXs or ISDN phones), the first to answer then receives
the call. For ISDN to behave this way, we have multimode.
What can I do with this now?
Patton Smartnodes are almost Swiss Army knives for do something VoIP on an existing ISDN setup. For example,
you can configure a Patton to mimic an ISDN device (use the TE port) and to handle calls to certain extensions on the
classic ISDN PBX or the ISDN line on a VoIP PBX. This can be useful, for example, to set up a complex IVR (which is
much more pleasant, on a VoIP PBX).
This is also useful if you want a backup line on a VoIP PBX to connect via ISDN in case of provider failure
SIP. Or, as a legal recourse, to have proper support for emergency calls.
If your business still thrives on fax communication, a smartnode connected to an ISDN line can make your VoIP network
at the fax test.
You can also place a Smartnode between a classic ISDN PBX (NT port) and the ISDN line (TE port). This is useful if, by
for example, you want to make international calls, or GSM calls, or on-site calls via SIP on an existing ISDN PBX, without
replace your existing PBX. Economists appreciate the return on investment you can achieve.
