IIntroducing
the ALMAZ (Diamond) Series Digital Switch - an optimal solution for
integration into new generation networks.
-
The
ALMAZ (Diamond) Series Digital Switch has been designed to take a full
advantage of new converging networks and existing POTS networks and the
flexible modular architecture of both hard-ware and soft-ware makes it a
powerful tool for construction of high-performance switching systems of
various subscribers' capacities and types.
-
The
main elements of the system architecture are the commutation and access
modules, who's scalable configuration permits step-by-step system capacity
expansion.
-
High platform reliability is ensured by distributed control and commutation
and redundancy of the main functional components (CPU, Power, Bus, etc)
-
Connection to digital networks is effected by PRI, E1 and E2 interfaces. PCM
interfaces support common channel signaling protocols (SS7, E-DSS1, QSIG)
and associated channel protocols (1 ACS, 2ACS), packet signaling protocols,
decade code, R2, R1.5, caller ID.
-
Connection to analogue networks is effected via 2- and 3-wire physical
lines, 4-wire connective lines from transmitting systems without ACS
signaling, 4/6/8-wire connective lines with 1 ACS, 2 ACS and E&M signaling.
-
Supervisor and monitoring services, automatic diagnostic systems, operative
search measures and packet commutation of speech traffic can be introduced
and performed.
Available in Expandable
Switches (from 4 - 56 E1's) and Fixed Switches (from 4 - 12 E1's) the
ALMAZ (Diamond) Series offers a unique opportunity to grow Telecoms
networks as required, install private exchanges and for VoIP carriers to
implement SS7 signaling with expansion flexibility and at very
affordable prices.
The ALMAZ (Diamond)
Series can be utilized in public, rural, private and dedicated
networks in a variety of applications:
Local sub-exchanges,
supporting exchanges, transit exchanges, Rural exchanges & private
exchanges. Technical characteristics are as follows:
