Product Description

TSM-32E16N8-ISO       This series of products is point-to-point optical transmission equipment developed
based on the dedicated very large scale integrated circuit developed by our company.
This product provides 32 Voice interfaces; 1-16 E1 interfaces; 8 Gigabit
Ethernet interfaces; each Ethernet electrical port has its own independent
Gigabit bandwidth; the total bandwidth of all 8 Ethernet channels is 8000M(8G),
through one optical fiber transmits, 8 channels of Gigabit Ethernet signals are
completely independent, do not affect and interfere with each other, that is,
physically isolated; and have 4 channels of RS232/422/485 interfaces(option); 2
optical interfaces (1+1 optical backup)(option) etc.; the internal circuit part
of the equipment adopts all-digital circuits. The whole machine works reliably
and stably, with low power consumption, high integration, small size and easy
installation and maintenance.

l     19-inch 1U rack-mounted, all-aluminum alloy, anodized casing, fanless heat dissipation design, IP40 protection grade;

l     Based on integrated circuits with independent intellectual property rights, the total bandwidth of optical fiber lines is 10G;

l     The optical port’s non-relay transmission distance can reach 2 to 120 kilometers; it provides 1+1 optical port backup function and dual optical port backup function to ensure uninterrupted business;

l     The E1 interface complies with G.703 recommendations and adopts fully digital clock recovery and smooth phase locking technology;

l     8-channel Gigabit Ethernet is 10/100/1000M, full/half duplex and fully adaptive. Each Ethernet electrical port has its own independent Gigabit bandwidth physical isolation;

l     Each Ethernet port supports Auto-MDIX (cross/direct line adaptive);

l     Gigabit Ethernet supports the transmission of VLAN ultra-long data packets and can be used with switch products that support the IEEE802.1Q protocol. It can support jumbo frame Ethernet packets with a maximum packet length of 10240;

l     32-channel voice access, supports caller ID function/reverse polarity billing/fax function; the phone supports mutual number allocation function for both sites;

l     The voice port supports FXO/FXS/24-line EM/24-line audio/magnet telephone interface. The FXO port is connected to the program-controlled switch, and the FXS port is connected to the user’s telephone;

l     The device has a power-down detection function, which can detect when the optical signal is lost, indicating that the peer device has lost power or the optical fiber is unavailable;

l     1 Console management interface (optional); 1 SNMP management interface (optional);

l    Multiple power supply modes are available: AC220V, DC-48V/DC24V, etc.; supports AC+DC; AC+AC; DC+DC and other dual power supply modes;
