executed in the same way, where the signal is transmitted simultaneously for all group
participants including public address amplifiers. CCS-IP2 returns to the initial ready-to talk
state, once the outgoing connection is completed. A subscriber’s response or voice calls
from other subscribers will be transmitted immediately to the CCS-IP2 loudspeaker.
In order to achieve optimum quality of communication, it is recommended to
maintain distance to the integrated microphone in the range of 20–40 cm, but no less than
12 cm.
Half-duplex communication mode with manual control of the receive/transmit
direction can be used within an IPN communication system, when communicating with
duplex user equipment, for example, telephone sets. In this case, communication between
the CCS-IP2 and the telephone set will be carried in both directions without disconnection
up until the pressing of the “End” key/button on the CCS-IP2, which is preprogrammed
during configuration.
During connection, the CCS-IP2 subscriber can control the direction of voice
transmission by pressing the key/button at the front panel for voice transmission from own
microphone to the telephone set. Upon releasing the key/button, the direction of voice
transmission will be reversed from the telephone set to the call station. As a result, the
conversation does not require further operations on the part of duplex subscriber.
The CCS-IP2 supports two SIP (RFC 3261) telecommunication protocols and the
Armtel-IP protocol. Operation of the device via the SIP protocol is carried out via the SIP
server. Calls over the SIP protocol occur in simplex mode, while call reception occurs in
half-duplex mode.
Incoming call and indication are limited when calling devices with the same priority.
The CCS-IP2 supports SNMP protocol (v2c version). The operation of the CCS-IP2
using this protocol allows you to integrate CCS-IP2 into third-party systems, as well as
organize device monitoring. During the work on this protocol, when the device status
changes (incoming / outgoing call, implementation of various group communication
scenarios: “Circular”, “Selector”, “Conference”, etc.), the communication application sends
device statuses (Trap) to the server SNMP monitoring.
Depending on the communication modes, the CCS-IP2 can organize various group
call scenarios: “Circular”, “Selector”, “Conference”, and also enables the User to manage the
connection and disconnection of discrete control lines on the RMLT.465275.006 ACM-IP2
Analog Subsystem Module remote device manufactured by Armtel LLC.
