Loop-09500 PTN

• The Loop-O9500R PTN/SDH/SONET/PDH IMAP (Integrated Multi-Services Access Platform) is an economical, all-in-one solution for integrating varioustypes 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.
