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 naming convention 1BIS2V means 1 ISDN NT port with 2 voice channels .
Number of channels
By default, you have 2 conversation channels , so you can have up to 2 simultaneous conversations .
Network connection
Your Patton SmartNode DTA has a network connection with a speed of 10/100 Mbps 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 undefeated in this
domain.
Call quality
An annoying problem that can occur during a call is echo or noise. For both problems, precautions were taken so that
you benefited from echo cancellation and a configurable jitter buffer.
NT or TE?
In ISDN, people like to use specific terminology which makes ISDN somewhat complex at first glance. But it's not
too bad, as long as you don't delve into the protocol.
You often hear the NT, TE and s0 buses. It's just that ISDN has two different ports. One network termination (NT) port and one port
terminating equipment (TE ) . You usually get the NT port from your ISDN line provider, the TE port is on your
ISDN telephone. And you should always connect a TE port to an NT port and vice versa. So, in simple language, 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
connect an ISDN telephone, you can provide an NT port for this purpose. If you want to connect a telephone exchange
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
nomenclature different 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
process an incoming call by various devices (for example, various telephone exchanges or ISDN telephones), the first one to answer then receives
the call. For ISDN to behave like this, we have multimode.
What can I do with this now?
Patton Smartnodes are almost Swiss army knives for doing something VoIP over an existing ISDN setup. For example,
you can configure a Patton to imitate an ISDN device (use the TE port) and to handle calls to certain extensions on the
classic ISDN exchange or the ISDN line on a VoIP exchange. 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 the event of a provider failure
SIP. Or, as a legal remedy, to have appropriate support for emergency calls.
If your business still thrives on fax communication, a smartnode connected to an ISDN line can make your VoIP network
fax- proof .
You can also place a Smartnode between a classic ISDN exchange (NT port) and the ISDN line (TE port). This is useful if, for
example, you want to make international calls, or GSM calls, or intra-site calls via SIP to an existing ISDN exchange, without
replace your existing exchange. Economists value the return on investment you can get.
