2 FOM FORTA155 Fiber Optic Multiplexer Scaleable capacity :supports 4, 8, 12, and 16 T1/E1 channels N*64 Kbps with V.35 Interface Embedded SNMP protocol 10/100 Ethernet interface Local and remote performance monitoring Auto Laser Shutdown (ALS) for personnel protection from hazardous laser radiation Redundant fibers to support 1+1 protection with sub 50ms switching capability Alarm/Error detection and Report Dimension (W x D x H) 439 x320 x 44mm Weight 4 kg ± 200 g Temperature Up to 95% (non condensing) Humidity Operation - 0 ~ 60 C / Storage - 10 ~ 80 C DC -48V DC / AC 100 ~ 260 VAC Voltage Consumption Protocol Self Diagnostic SNMP V2C Memory diagnostic Various Loopback capabilities FORTA 155 is a stand-alone STM-1 Optical Multiplexer that provides 4/8/12/16 lines of T1/E1 tributary interfaces, a V.35 (Nx64Kbps) leased line interface, and an Ethernet over SDH interface. Each of FORTA 155 s T1/E1 tributary modules provides 4 lines of E1/T1, and the interfaces can be configured to E1 or T1, depending on individual requirements. A maximum of up to 16 lines of T1/E1 interfaces can be provided. FORTA 155 assists service providers to deploy swift setup of optical networks, and to extend their CO interfaces to support remote sites, which resolves issues such as line shortage, and transmission distance limitations. FORTA 155 adopts the FTTB (fiber to the building) and FTTC (fiber-to-the-curb) optical network architecture. Together with other telecommunication devices that include E1/T1 interfaces, such as the E1 Multiplexer, DLC, Fractional E1/T1, and PABX, FORTA 155 can provide connections to various user sites, such as commercial towers, residential buildings, remote towns, mobile phone base stations, hospitals, and schools. FORTA 155 s transparent transmission technology works by multiplexing E1/T1 signals onto a single mode optical high-speed network; this will provide a wide range of telephone, data and video services. FORTA 155 s modular design conveniently allows network planning divisions to invest at their own paces. FORTA 155 s Ethernet interface allows service providers to operate under their existing TDM infrastructure, which will enable providers to reuse the network facilities on hand. It also allows providers to increase modules, or upgrade software at their own pace, according to their individual planning schedules and customer requirements, which will enable existing TDM networks to seamlessly migrate to a Next Generation IP Network. FORTA 155 s built-in SNMP Agent includes Ethernet interfaces, which connect to the SNMP Network Management System. Userfriendly graphical interfaces (GUI) offer a comprehensive range of OAM & P functions such as configuration, maintenance, fault management, performance monitoring, and security management. This richly integrated system simplifies operation procedures, and cuts down on operational cost, thus helping service providers to manage and update their network with ease and efficiency.

3 ETH 10/100 Ethernet Module Ethernet over SDH Functions The ETH Module provides Ethernet over SDH functions that conform to ITU-T G.7041 Generic Framing Procedure (GFP), and ITU-T X.86 Link Access Procedure- SDH(LAPS). It also supports the IEEE /100 Ethernet network interface. ETH provides auto-sensing 10/100 Mbps switching capabilities for efficient connectivity to servers, workstations and others attached devices. Plug-and-Play usability, outstanding priceto-performance ratio, and flexible designs makes ETH a simple and affordable solution for a wide range of applications. The IEEE 802.3x standard-based flow control allows ETH to prevent traffic congestion by informing attached devices to halt transmission. When ETH detects that the buffer of each port is nearly full, attached devices are requested to wait until new data can be accepted. Flow control allows 100 Mbps full duplex connections between servers and ETH, with minimum data transfer loss. Enable the IP traffic tunnel through the existing SDH network Realize the Ethernet all the way network infrastructure Conforms to IEEE 802.3, 802.3u, and 802.3x Ethernet Standards Half-duplex mode for backpressure, and Full-duplex for flow control Reduce the cost of operating and maintenance with high performance SNMP management Ports One uers port per card Protocol CSMA/CD Data buffer 2 Mb/s Bandwidth 64 Kbps ~ 100 Mbps by 64 kbps increments Packet Size Up to 1536bytes Mapping Format GFP or X.86 FOI Fiber Optical Interface Module Standard SDH STM-1 Transmission The FOI Module provides a STM-1 ( Mbps) interface. FOI also provides 1+1 protection switching to maintain transportation stability, as well as a SCNP protection mechanism which meets ITU-T.G.841 standards. FOI also supports the manual set-up switch mode. Based on performance monitoring, a protection switch threshold can be set up, to indicate major alarms when the protection switch occurs. Through the FOI Module, message and system information from the remote terminal will be sent back to the local terminal. Users can use RS- 232 interface to connect to the CIT (Craft Interface Terminal), to control the remote terminal or retrieve the system status and remote alarms. It also connects to the network management system via Ethernet, to provide a Graphical User Interface. The operation team can set up all kinds of operation parameters, warning and operation controls, and the monitoring of transport functions. Front panel LEDs indicate errors, alarms, and network connection status. STM-1 Optic Modules conform to ITU-T G.957 standards.

4 QET Quad E1/T1 Tributary Module Four Lines of E1/T1 Modules FORTA155 s QET (Quad E1/T1) tributary module offer s two tributary interfaces---t1 or E1 interfaces, which comply to 2,048 Kbit/s or 1,544 Kbit/s interface standards from ITU-T G.703/G.704/G.706. QET s Monitoring functions include data collection, and generation of near end and far end efficiency parameters such as Error Second (ES), Severely Error Second (SES), and Unavailable Second (UAS). This information includes current and the most recent 96 bits of 15-minute historical data for CV, ES, SES and UAS. QET modules support hot-swappable functions. Adding or changing modules during transmission will not affect ongoing services of T1/E1 modules. When modules are changed, or after power recovery, the system will automatically upload the settings of the previous module, so that no re-setup is necessary. Module Service signal LEDs (MODE), and E1/T1 signal lights are located on FORTA 155 s front panel. Quad E1/T1 links per Module Supports AMI or HDB3 Line Coding Configurable to serve as a Tributary Module, Trunking Module, or V5.2 E1 Interface LED signals indicate Module status Supports grooming for Nx64 Kbps Input Jitter Tolerance complies with ITU-T G.823 Includes Lightening Protection circuits Alarm/Error detection and reporting Nx64 V35 Module Nx64 Digital Transmission Interface E1 Interface Data Rate 2048 Kbit/s ± 50 ppm Line Coding ITU-T G.703 AMI or HDB3 Standards ITU-T G.703, G.704, 706 Impedance 120Ω / 75Ω T1 Interface Data Rate 1544 Kbit/s ± 50 ppm Line Coding AMI andb8zs Standards ITU-T G.704 Impedance 100Ω The NX64 module supports Nx64 (N=1~31) data leased line services. The data rate provided by NX64 can be selectable from 64Kbps to 2.048Mbps in 64k increments. Each NX64 card provides four NX64 user ports. NX64 is a multi-protocol data service card, and it will support V.35, X.21 or RS-530. Users can easily select the desired application from the CIT or NMS interface. Via an optical link, this data service line card can allow service providers to offer leased line services to their customers in remote areas far away from the central office. Various diagnostic loop back tests are also provided in NX64, and which can assist field engineers and operators in troubleshooting, at field sites. FORTA also works as an SNMP agent, and uses a user-friendly Graphical User Interface (GUI) to connect with the counterpart of a SNMP manager.
