ict fe1-v35/10bt converter gives the interface conversion between g.703 e1 (framed and unframed) and v.35/10base-t. when used as an interface converter or digital access solution for unframed e1 and framed e1 network services, interface conversion between v.35 and g.703 e1, and between 10base-t and g.703 e1 is field selectable, combining fe1/v35 and fe1/10bt in one machine. when used as a mini pcm multiplexer, ict fe1-v35/10bt can aggregate/multiplex the 10base-t and v.35 channels over the single e1 network link, ideal for such application as connecting router with v.35 port and lan simultaneously over one single e1 link. the main e1 link may be clocked from the recovered receive clock, from the data port clock, or from the internal oscillator. for easy maintenance and status monitoring, the device provides local and remote loop back tests and a comprehensive array of front panel led indicators. ict fe1-v35/10bt is widely used in communication network for both wan and lan applications. features: ø interface conversion between e1 and v.35, and e1 and ethernet ø support itu-t v.35, g.703, g.704, g.823 ø fully compliance with ieee 802.3 and ethernet standards ø framed (nx64kbps) and unframed (2.048mbps) selectable, support continuous and discontinuous timeslots setting ø framed mode support pcm30/ pcm31 ø ethernet port 10mbps, full/half duplex mode compatible ø 10base-t lan interface on rj-45 connector and mdi/mdi-x auto-crossover ø 1k mac addresses table, with automatic address learning and aging capability ø crc/non-crc auto-negotiation on e1 interface ø support remote bandwidth control, and remote loop back test under framed mode ø support internal clock, e1 recovery clock or v.35 line clock ø provide local analog loop back, local digital loop back and remote loop back test ø for e1 interface, 75 ohm (unbalanced) and 120 ohm (balanced) available ø for v.35 interface, dce and dte mode selectable ø comprehensive front panel led indicators for easy status monitoring and diagnosis ø -48vdc& 220vac power supply options available specifications e1 interface standard itu-t g.703, g.704 line type unloaded 4-wire twisted pair 19 to 26 awg or bnc 75Ω coaxial cable line code hdb3 baud rate unframed: 2mbps, full duplex, sync framed: n x 64kbps (n=1~31) framing unframed / framed selectable transmit level according to g.703 jitter performance compliant with itu-t g.742 and g.823 impedance 75Ω unbalanced (bnc coax) 120Ω balanced (rj-45 twisted pair) receive voltage 0~-43 db transmit high voltage 2.37±10%, 75Ω transmit low voltage 0±0.1v connector rj-45:120Ω balanced bnc coax:75Ω unbalanced v.35 interface date rate n×64kbps n = 1 ~ 31 in pcm31 (ccs) mode n = 1 ~ 30 in pcm30 (cas) mode jitter performance: compliant with itu-t v.35 standard operation mode dte / dce selectable type and connector v.35 (db25, female) ethernet interface baud rate 10mbps, half / full duplex, auto-negotiation compliance ieee802.3, 802.3x vlan support support vlan data package up to 1.6k byte type and connector rj45, mdi / mdi-x auto-negotiation physical height 36 mm / 1.4 in width 252 mm / 9.8 in depth 136 mm / 5.3 in weight 1.0kg / 2.2lb power supply ac source 220 vac (±10%), 50 to 60 hz, 0.4 – 0.2a dc source -48 vdc (-36 to -72 vdc), 0.4a power consumption ≤ 5w environment operation temperature 0 - 50°c storage temperature -20 ~ 60℃ relative humidity up to 95%, non-condensing
