Import Fast Ethernet Lans Over E3 Or T3 Converter — Buy in Bulk from Supplier in China

The Fast Ethernet LANs over E3 or T3 converter is a network termination unit that bridges 10/100BASE-TX Ethernet to existing E3 or T3 TDM circuits. It provides one unframed E3 port or one framed T3 port together with a single 10/100BASE-TX Ethernet port. The device forwards packets at wire speed, fully utilising the 34.368 Mbps E3 or 44.736 Mbps T3 bandwidth. Power can be supplied from 220 V AC (±10 % 50 Hz) or, optionally, from a -48 V DC source, with a consumption of 5 W.

The converter complies with ITU-G.703 for the E3 interface and with GR-499-CORE, ANSI T1.107 and ANSI T1.102 for the T3 interface, using HDB3 and B3ZS line codes respectively. Typical network-level converters in this class support both 10 Mbps and 100 Mbps Ethernet, consume between 3 W and 7 W, and operate within -10 °C to 50 °C and 10 %‑90 % relative humidity. The front panel includes LED indicators for link status, fault propagation and diagnostic data, allowing rapid field troubleshooting. The unit is supplied in a single carton and is intended for point-to-point applications such as inter‑office or enterprise LAN extensions over leased TDM lines.

Network providers and enterprise network engineers typically select this type of converter to extend Ethernet services to remote sites without laying new fibre. Buyers should confirm the minimum order quantity, lead time and incoterms directly with Changzhou Bell Data Communication Equipment Co., Ltd. The supplier is listed as an imported tier with a harbour trust tier, but its response rate is currently recorded as zero, so trade negotiations may require proactive follow‑up.

Changzhou Bell Data Communication Equipment Co., Ltd. is located at #15A Zhongnan Building #33 Guanhe West Road, Changzhou 213002, Jiangsu, China. It is registered as an imported tier supplier and carries a harbour trust tier, indicating that the platform’s verification process has identified basic commercial credibility.

The company’s public profile does not disclose production capacity, certifications or client list, and its recorded response rate is 0 % with no average response time, suggesting that enquiries may require repeated follow‑up. Prospective importers should therefore request up‑to‑date documentation and confirm the availability of technical support before placing an order.
