MP-2100M-ML-1E1 and MP-2100M-ML-2E1 electrical copper interface and the MP-2100M-MLF-1E1 and MP-2100M-MLF-2E1 fiber optic interface family of main link modules
The MP-2100M-ML-1E1 and MP-2100M-ML-2E1 electrical copper interface and the MP-2100M-MLF-1E1 and MP-2100M-MLF-2E1 fiber optic interface family of main link modules enable direct connection of RAD Megaplex-2100/2104 to one or two E1 lines. Multiple main link modules can be installed in a single chassis, providing Megaplex-2100 with up to four full E1 link capacity, for both point-to-point and point-to-multipoint applications. Alternatively, multiple
Fractional E1 links can be supported.
The E1 ring functionality can be configured in a single database, allowing an unlimited number of nodes per ring with protection speed of up to 5 seconds. E1 link modules are compatible with all carrier-provided E1 services, meeting the requirements of ITU-T Recommendations G.703, G.704 and G.732. They support both two (256N) and 16 (256S) frames per multiframe formats. CRC-4 and E bit are also supported, complying with G.704 recommendations. Zero suppression over the lines is HDB3.
The fiber optic interface MP-2100M-MLF-1E1 and MP-2100M-MLF-2E1 main link modules enable direct connection of the RAD Megaplex-2100 to fiber optic lines, eliminating the need for an external fiber optic modem or repeater. Links of these modules operate at E1 (2.048 Mbps) , providing secure links in hazardous or hostile environments. With ( MP-2100M-MLF-1E1 or MP-2100M-MLF-2E1) modules, the E1 electrical signal is converted into a transmitted optical signal using a LED or laser. At the opposite end of the fiber line, the optical signal is converted back into an electrical signal and amplified to the required level by the remote MP-2100M-MLF-1E1 and MP-2100M-MLF-2E1 module.
The following optical interfaces are available for the RAD MP-2100M-MLF-1E1 or MP-2100M-MLF-2E1 modules:
• 850 nm laser for use over multimode fiber with typical distances of up to 5 km (3 miles)
• 1310 nm laser diode for use over single mode fibers for extended range of up to 62 km (38 miles)
• 1550 nm laser diode for use over single mode fibers for maximum range of up to 100 km (62 miles) Interfaces are terminated with a pair of ST, FC/PC or SC type connectors (see
Ordering section of the data sheet).
MP-2100M-MLF-1E1 and MP-2100M-MLF-2E1 modules are compatible with RAD’s standalone fiber modem FOM-E1/T1, as well as with fiber modules of FCD, DXC and other RAD Megaplex systems. The internal cross-connect matrix of the MP-2100M-ML-1E1, MP-2100M-ML-2E1, MP-2100M-MLF-1E1 and MP-2100M-MLF-2E1 main link modules routes voice and data channels from any I/O module installed in the chassis, to any installed main link. The matrix can route voice and data traffic from any link to any other link. The non-blocking full cross-connect feature enables flexible timeslot assignment and efficient utilization of E1 bandwidth, and also facilitates drop & insert, bypass or broadcast multi-link applications.
Note: A total of 124 timeslots can be allocated, either for transmission of I/O channels or for bypassing timeslots between links of different modules.
Additional main link modules can be installed in the Megaplex-2100 chassis to operate as hot standby modules. The backup module’s links and the active module’s links are connected to the same E1/T1 lines via Y-cables, providing full redundancy in case of main link hardware failure. Alternatively, multiple links can be configured for load sharing with optional priority bumping, ensuring continuous operation of the most important channels if one of the links fails.
Extensive transmission reliability can be provided by 1:1 protective switching between any two links in case of line failure. 1:1 protective switching between the two links of a dual link module takes place within 50 msec of a link failure. A Megaplex chassis can be equipped with a combination of fiber and non-fiber main link modules.
In the MP-2100M-ML-2E1, an optional port bypass relay interconnects between both E1 main links when the module is not powered. This feature is designed to enable critical traffic (such as inband network management bits) to pass undisrupted through the links of a non-powered unit, to other units connected in a daisy chain topology.
Note: The bypass relay is not to be used in the Ycable protection mode.
The electrical copper interface MP-2100M-ML-1E1 and MP-2100M-ML-2E1 and fiber optic interface MP-2100M-MLF-1E1 and MP-2100M-MLF-2E1 link modules support R2 signaling with transparent MFC/DECADIC for setting up, metering and disconnecting phone calls. This enables placing a Megaplex-2100 between an older R2-PBX and a digital (E1-CAS) PBX. In addition to the ITU-T standard R2 protocol, several predefined national PTT protocols, as well as user-definable variations, are also supported.
The electrical copper interface MP-2100M-ML-1E1 and MP-2100M-ML-2E1 and fiber optic interface MP-2100M-MLF-1E1 and MP-2100M-MLF-2E1 link modules support the V5.1 inband protocol to connect PSTN and ISDN residential and SOHO users to V5.1 local exchanges. V5, the ETSI standard interface, operates between the access network and the switch for basic telephony, ISDN and semi-permanent
V5.1 support provides the same types of services and features that are available to PSTN or ISDN subscribers directly connected to the exchange subscriber ports, to those that are connected via the
Megaplex-2100 E1 links. System timing can be derived from an external station clock. This clock can then be passed to other connected Megaplex units. A dedicated RJ-45 connector is provided on the module panel for receiving the external station clock signal.
Note: The station clock connector is not provided on dual-link fiber MLF modules.
Diagnostic capabilities of dual-port ( MP-2100M-ML-2E1 and MP-2100M-MLF-2E1 ) modules feature local and remote loopbacks on each module port, local and remote loopbacks per timeslot (including
split timeslots), and BER tests per port and per timeslot. Single-port modules feature local and remote loopbacks on each module port. Performance statistics for each of the two main links may be
obtained and analyzed via the Megaplex-2100 management system.
Main link and system parameters are monitored and controlled via a terminal interface, or via the RADview Element Management System.
