The fiber-optic linear path of secondary Pcp level.
Primary functions: trunking of four-component E1 streams (2 048 Kbit/s, G.703) into the E2 aggregate stream (8 448 Kbit/s) and its transmission and reception via single-and multimode fiber-optic cable.
Polycom-240 is a simple and effective solution for multiplexing/demultiplexing of E1 streams.
Polycom-240 is designed for operation on all areas of Russian telecom network, technological telecom network. Performance, operation and control over the equipment do not depend on the existence or state of equipment for formation of the primary digital channels.
Polycom-240 - provides indicators of network jitter in accordance with ITU-T G.823 Recommendation.
Polycom-240 - performs analysis of signals of E1 and E2 joints in accordance with ITU-T G.775 Recommendation.
Polycom-240 - performs trunking of secondary Pcp level by positive alignment of speeds in accordance with ITU-T G.747 Recommendation.
Polycom-240 - provides transmission and reception of E2 group signal via electric coaxial cable with attenuation up to 6 Db.
Polycom-240 - provides acoustic alarm and indication of emergency and pre-emergency status of the equipment, as well as announcement to external devices on the joint of the " public key".
Features:
- Multiplexing of 4 primary digital streams at speeds of 2 048 Kbit/s (E1) into one stream of 8 448 Kbit/s (E2);
- protection of the reception and transmission E1 and E2 joints from short circuits and overvoltage;
- low power consumption (less than 6 Watts);
- Power lock with key (security switchlocks);
- easy installation and maintenance, no adjusting operations;
- attractive weight-size parameters;
- 3 years warranty.
