Overview of NP2GE-B, NP2GE-A, and NP2GE
1 Overview of NP2GE-B, NP2GE-A, and NP2GEMain functions of NP2GE-B, NP2GE-A and NP2GENP2GE-B, NP2GE-A, and NP2GE are the interface plug-in units that are designed for optimized use of IP usage and packet environment. The NP2GE-B, NP2GE-A, and NP2GE units are targeted for multiprotocol transport over the Iu-PS and Iu-CS inter-faces. The primary transport method is IP over Ethernet.The NP2GE-B, NP2GE-A, and NP2GE units provide multiprotocol packet processing at wire speed and Ethernet connectivity by using electrical and optical interfaces. The high processing power of the network processor and the unit computer in the NP2GE, NP2GE-A, and NP2GE units enables to process protocol and data at the line interface unit (LIU) instead of the dedicated processing units.The NP2GE and NP2GE-A units are only used in MGW, the NP2GE-B unit is used in both RNC and MGW.

NP2GE-B, NP2GE-A, and NP2GE Capacity and performance of NP2GE-B, NP2GE-A,and NP2GE
Id:0900d805808d5419Confidential
2 Capacity and performance of NP2GE-B, NP2GE-A, and NP2GEThe NP2GE-B, NP2GE-A, and NP2GE units have two 1000Base-SX/LX (optical) and two 1000Base-T (electrical) Gigabit Ethernet interfaces. The Ethernet interfaces are compliant with the IEEE802.3 specifications.
The optical 1000Base-SX is designed to support distances of 2 to 550 m with 50 m MMF, 2 to 275 m with 62.5 m MMF. The optical 1000Base-LX interface is designed to support distances of up to 10 km. However, the exact transmission distance of the optical interface depends on fibre loss, connector and splice loss, the output level of optical transmitter, and the minimum optical power on the receiver. The optical interface is optimized for 10 m single-mode fibre, but multimode fibres can also be used for short distances.
The 2.5 G switch fabric interface has the following capacity and performance:
The line rate of the high-speed ports is 2.488 Gbit/s. However, because of the various cell overheads, the usable bandwidth is lower.
With the 64-byte fabric cell size, the interface throughput is 3904000 cells/s. The cell rate of 3904000 cells/s translates into 1.655 Gbit/s of ATM throughput (3904000 x 53 x 8).
The cable length is up to 5 m.
g The NP2GE-B, NP2GE-A, and NP2GE plug-in units can only operate at 1000 Mbit/s, cannot operate at lower rates, for example 100 Mit/s.

Structure of NP2GE-B, NP2GE-A, and NP2GE
3 Structure of NP2GE-B, NP2GE-A, and NP2GE
3.1 Mechanical structure of NP2GE-B, NP2GE-A, and NP2GEThe NP2GE-B, NP2GE-A, and NP2GE plug-in units are implemented with a single standard IPA2800 full size printed wiring board (PWB). The size of the PWB is 265 mm x 285 mm (height x length). The nominal thickness of the board is 2.0 mm.
The NP2GE-B, NP2GE-A, and NP2GE plug-in units also have a full-sized heat sink, which enhances the cooling performance of the hardware components.
The NP2GE-B, NP2GE-A, and NP2GE plug-in units weigh approximately 1.6 kg.
3.2 Logical structure of NP2GE-B, NP2GE-A, and NP2GEThe NP2GE-B, NP2GE-A, and NP2GE plug-in units consist of the following functional blocks (block names in parentheses after the name):
dual 1000Base physical layer (PL2GE) dual Fast Ethernet physical layer (PL2FE) network processor and memory (NP5G) ATM message channel multiplexer/demultiplexer (AMEBA) 2.5 G Switch fabric interface (SD2G5) unit computer (PQ3CC) refresh phase-locked loop (RFP) hardware management system slave node (HMSS) Ethernet physical layer blocks (ETH) distributed DC/DC converters (DC/DC)
3.3 Interfaces of NP2GE-B, NP2GE-A, and NP2GEExternal interfaces1000Base-T
The 1000Base-T interface performs full duplex baseband transmission over four pairs of the category 5 cable. The 1000Base-T interfaces that are located in the front panel are implemented with shielded RJ45 connectors.
1000Base-SX
The 1000Base-SX multi-mode transceiver is compliant with IEEE802.3z optical inter-face specifications. The transceiver fulfils the Class 1 laser safety standard, as required by IEC-60825-1 with 850 nm laser.
1000Base-LX
The 1000Base-LX single mode transceiver is compliant with IEEE802.3z optical inter-face specifications. The transceiver fulfils the Class 1 laser safety standard, as required by IEC-60825-1 with 1310 nm laser.
The 1000Base-SX/LX connector type is LC duplex. The LC cable connector is placed with a 90 degree boot to comply with the IPA2800 75 mm front cabling space. Each optical connector has its own fibre for Tx and Rx directions.

Interfaces to other unitsFast Ethernet physical layer interface
The two 10/100 Mbit/s Fast Ethernet physical layer interfaces are intended for IPA2800 network element internal use only.
2.5 G Switch fabric interface
The redundant 2.5 Gbit/s serial switch fabric port interface is implemented via the back-plane connector J5. The switch fabric port is connected from the backplane to a back interface unit which has Small Form-factor Pluggables (SFP) modules. There are alto-gether four backplane bridge SerDes interfaces, of which two interfaces are connected to the working unit and two to the spare unit.
The SFP interface is designed for hot swapping. The NP2GE-B, NP2GE-A, and NP2GE plug-in units can be connected to the switch fabric for example with 2.5 Gbit/s Infini-Band cables and transceivers.The SFP direct attack connector uses a copper cable.
Synchronization and Timing interface
The synchronization and timing interface connects the Refresh PLL block to TBUF or TSS3 plug-in units, which serve as an external timing source. The interface has two 19.44 MHz inputs, one of which is for active source and the other for redundant source.
Hardware Management System interface
The hardware management system slave (HMSS) node of the NP2GE-B, NP2GE-A, and NP2GE plug-in units has an external connection, which connects it to the hardware management bus (HMS). The HMS bus consists of a master node and one or more slave and bridge nodes. The HMS bus uses the controller area network (CAN) protocol.
Ethernet-based message bus
The two 10/100 Mbit/s Ethernet-based message buses (EMB) are intended for the future Ethernet-based messaging.
Debug and service terminal interfaces
The debug and RS-232 service terminal interfaces, provided by the unit computer, are used for finding and removing the causes of failures.
The debug interface is implemented by one of the ETH blocks, which can also be used for EMB. However, the ETH block cannot be used simultaneously for debugging and the EMB, because both the EMB and debug interface use the same internal interface towards the unit computer.
Figure 1 Interfaces of NP2GE-B, NP2GE-A, and NP2GE shows the interfaces of the NP2GE-B, NP2GE-A, and NP2GE plug-in units.

Figure 2 Front panel of NP2GE-B, NP2GE-A, and NP2GE
The NP2GE-B, NP2GE-A, and NP2GE plug-in units have five connectors in the front panel: two 1000Base-T connectors (2 x shielded right angle RJ-45 connectors), two pluggable 1000Base-SX/LX connectors (2 x SFP standard cages and optical transceiv-ers), and one for the service terminal (RS-232) connector. The 1000Base-SX/LX trans-ceiver can be hot swapped from the front panel.
f WARNING! Risk of eye damage caused by invisible laser beam.Do not look inside the optical connectors of the plug-in unit.
Note that only one type of interface can be used at the same time. Selection of opti-cal/electrical interface is fully automatic and based on port activity sensing and priority (if both ports show activity, optical is preferred). That is, when the customer connects
