Loop Telecom

Founding

In 1991, a group of established professionals from the communications industry founded Loop Telecom. These industry leaders, with decades of experience and years of service at Verizon, Tellabs and AT&T, realized the largely untapped engineering and production capabilities of Taiwan. Just ten years after founding, with its Western-style engineering and management, Loop Telecom met the earnings, market, and product diversity requirements to go public with its IPO. It is currently traded on the Taiwan Stock Exchange Corp., or TSEC (3025).

After finding success in its initial market coverage of just a few countries, including the United States and Taiwan, Loop Telecom has expanded its market outreach to over 80 countries around the world. Several sales offices have been established including Taiwan, France, the United States and Australia. Several TAC centers (Technical Assistant Center) have been setup including TAC-EMEA in Greece covering EMEA, TAC-USA in USA covering North America and TAC-ESAF in Kenya covering East and South Africa.

O9500R

The Loop-O9500R PTN/SDH/SONET/PDH IMAP (Integrated Multi-Services Access Platform) is an economical, all-in-one solution for integrating various types of signals and transportation over various types of networks within one enclosure. Its universal roles and modular design make it effortless to perform traffic grooming for both peripheral and core networks by providing access interfaces, multiplexing, cross-connection, gateways, and transportation channels.

For access interfaces, 10+ low-speed modules are designed to encapsulate industry specific signals into DS0 timeslots. These interfaces include Voice (e.g. FXS, FXO, E&M, and etc.), Digital (e.g. RS232, RS449, X.21, and etc.), Teleprotection (e.g. G.703, C37.94) and so on.

For multiplexing and cross-connection, O9500R provides non-blocking cross-connection of up to 672 DS0 timeslots, which equal to 21 E1 channels, to serve as a MUX/DACS, and VC-n/VT-n fabric for SDH/SONET non-blocking cross-connection to serve as an ADM.

For transportation, high-speed modules provide transportation channels such as 10Gb MPLS/Carrier Ethernet/IP switching and routing from PTN10G card, STM-1/4/16(OC-3/12/48) channels from Controller, B155/622, and B2G5 cards, Optical channels from 7-port FOM cards, E1/T1 channels from 63-port E1/T1 cards, and E3/T3 channels from 3-port E3/T3 cards.

For gateways, the signals from different interfaces can be freely encapsulated, cross-connected, and transported over a variety of transportation networks. For instance, E1/T1 and E3/T3 channels can be encapsulated into VT/VC paths and transported over SDH/SONET. Modules such as TDMoE and 8GESW make it possible for TDM traffic to be transported over Ethernet (DS0 over Ethernet) and the other way around (Ethernet over SDH/SONET) via circuit emulation and virtual concatenation technologies. Using the PTN10G card, SDH/SONET and DS0 circuits can also be encapsulated for packet network transportation.

Multiple protection schemes are designed at different levels, including path-level SNCP/UPSR and section-level MSP (1+1) for SDH/SONET, circuit and line protection for access interfaces, DS0 SNCP/UPSR and ULSR for low-speed modules, MPLS-TP with two LSPs per tunnel, ELPS and ERPS, and 1+1 module redundancy for power, controller, and plug-in cards.
Performance and fault are also monitored to ensure service integrity. Operation, Administration, Maintenance and Provisioning (OAM&P). These functionalities are fully incorporated into the operation system. O9500R is fully compatible with Loop-iNET (EMS) and Loop-iNMS (Integrated NMS) to achieve centralized management for large scale networks.

G7800

G7800 supports both MPLS-TP and Carrier Ethernet (EPL, EVPL, EPLAN, EVC defined in MEF) for packet transportation, as well as advanced L3 features for enterprise network services. In addition to native Ethernet transport, G7800 can be used as the gateway for PDH and SDH/SONET networks to enter PSNs using Circuit Emulation and Encapsulation technologies. Encapsulation technologies include TDMoE, TDMoIP, and TDMoMPLS. Circuit Emulation include CESoPSN (NxDS0/64K), SAToP (Unframed E1/T1), and CEP (SDH/SONET paths). Pseudowires make grooming and multiplexing DS0, E1/T1, and SDH/SONET paths easier, and service integrity can also be monitored and protected via packet network protection schemes.

One G7800 with core switching bandwidth up to 400Gbps supports 100GE, 40GE, 10GE and 1GE along with additional TDM interfaces, including STM-n/OC-n, E1/T1, and a rich variety of low-speed DS0 interfaces. The system is a perfect combination of PTN/CE, SDH, and PDH technologies.

G7800 provides high availability and reliability required by Carrier, Power Utility, Military, Government and Transportation applications by supporting MPLS-TP LSP 1:1/1+1 protection and ERPS, with protection switching time <50ms. Ethernet and MPLS section and end-to-end OAM are also provided for monitoring service integrity and performance. The G7800 is 7U in height, and its powerful functions enable customers to provision a service-grooming hub, ring, or mesh 10G packet network with ultimate ease.
G7800 comes with an environmentally friendly design. G7800 devices are products with low pollution. 90% of the metal structure uses low-pollution stainless steel and aluminum plates, which is more environmentally friendly than materials used in previous products. It also comes with detachable design, for easy assembly and disassembly. G7800 also comes with recyclable design; after it reaches end of life, its components can be dismantled for reuse, recycling, energy recovery, or other non-wasteful means.
