1. INTRODUCTION.
1.1. Applications of this product.
SYSTEL IP is a “call-in” system with multiconference capability that drastically reduces the
costs for this type of communications. Further, it significantly improves the audio quality,
increases the flexibility and integration with already existing telephone systems at the station.
The investment required is very small and will be amortized very rapidly through simple saving
of costs.
Business telephone systems are rapidly migrating to VoIP technology, integrating IP
switchboards, Asterisk or similar type distributed, or virtual, allowing access to new alternative
telecommunication service providers. At the same time telephony or call-in systems for
broadcast applications have so far been an isolated island with important operational costs and
stagnant technology.
SYSTEL IP allows for the integration of broadcast telephony with the existing corporative, IP
based PBX, thus avoiding the need to keep conventional phone lines exclusively for broadcast
use.
1.2. Description of the basic system: SYSTEL IP 4 - SYSTEL IP 12.
The heart of the system is a 19” rack unit, in two versions:
•
Systel IP 4, one unit high rack for 4 simultaneous IP phone lines. Includes: voice and
control IP connectors, 2 analog inputs and 2 analog outputs, 1 input and 1 output -both
selectable as analog or digital-, a handset port, another port -which can be used as the
second handset or the second analog input and output-, 4 GPI and 4 GPO. This should
be enough to provide service to one or two studios.
•
Systel IP 12, two units high rack format, for 12 simultaneous IP phone lines. Includes
voice and control IP connectors, 8 analog inputs and outputs, 4 digital inputs and 4 digital
outputs, 4 handset ports, 12 GPI and 12 GPO. This should be enough to cover 4 studios.
Both units behave like multi-line IP Phones with SIP signalling protocol. Compatible with
Asterisk PBX, SIP Trunking and virtual PBX. Analogue and ISDN lines supported through
gateways.
Encryption algorithms include the proper ones in telephony: G726, G729 and low bit rate G711
with higher quality. G722 also incorporate coding with extended bandwidth to 7 kHz, which
characterize them as "HD" and makes them compatible with N / ACIP AudioCodecs and SIPPhones (Any AEQ Phoenix AudioCodec and most PC telephony software).
They are provided with configuration software, which can be run in several computers on a
single system, web server and web client for an unlimited number of terminals.
IMPORTANT NOTE: The default IP address, configured in the units as they leave the Factory,
is 172.26.36.250 in the case of Systel IP 4 and 172.26.35.250 in the case of Systel IP 12.
