The DM705-SUB is a flexible multiservice PDH multiplexer with access, transport and cross connection interfaces. It allows the interconnection of sub rate data and voice traffic into the E1, SHDSL and SDH network. Its 4U chassis can be installed in 19’’ racks. Frontal connections are available and it supports hot swap of all modules. It can operate with redundant power supply and CPU.
The QX series PDH multiplexers can combine various digital access interfaces into multiple E1 or T1 lines for convenient transport and switching. They are supplied in 5U, 2.5U, and 2U chassis. The QX 3440 multiplexers have redundancy for the CPU, E1 and power.
QX3440-D Compact PDH Multiplexer
The 2U chassis QX3440-D is a 36 E1 or T1 PDH Multiplexer that can combine various digital access interfaces into multiples E1 or T1 lines for convenient transport and switching. 9 half slots provide access for a variety of interfaces, including RS232, V.35, V36, RS422, RS485, E&M, FXS, and FXO. Up to 72Mbps or 36 x 31 TS could be cross-connected in this devices.
The DM4E1 is a PDH multiplexer in conformity with G.751 and G.742 standards. It multiplexes E1 channels, Ethernet, V.11 and E3 in optical or electrical 34M beams.
The DM4E1S is an optical modem with solutions for end-to-end communications and capable of simultaneously connecting up to 4 independent aggregates. Also capable of connecting up to 6 tributaries of up to 2,048kbit/s, directing them to any of the available aggregate positions.
The DM16E1 is a PDH multiplexer in conformity with G.751 and G.742 standards. It multiplexes E1 channels, Ethernet, V.11 and E3 in optical or electrical 34M beams.
The MX-4EM is a fibre optic multiplexer that Carries 4 E&M analogue interfaces and one E1 G704 CAS. The E&M interfaces permits the interconnection of equipment within the voice band 300-3400 Hz like: voice, modem, PBX LIA, analogue Radio, SCADA, etc. The MX 4EM can be a low cost solution to support analogue interfaces in a small density of applications concentrated in large PDH multiplexer.
The MX-E3T3 is a PDH, E3/T3 multiplexer to 16 or 21 E1/28 T1 interfaces. The MX-E3T3 provides a simple and cost effective solution for transporting multiple E1/T1 over a single 34/45M data stream in a Telco or industrial environment. The MX-E3T3 provides multiple solutions in a single box.
