Overview

Introduction

MSR 50 Routers were self-developed by our company for use on enterprise-level networks. Depending on

the network size, MSR 50 Routers can be either core routers on small and medium enterprise networks,

or access routers for network branches on some large-sized enterprise networks. Therefore, MSR 50

Routers are suitable for the application on the carrier-level networks, such as telecom management

networks and billing networks. MSR 50 Routers adopt modular design and support a wide range of

optional interface cards and service modules, including flexible interface card (FIC), smart interface card

(SIC), multi-service card A (MSCA), multi-service card B (MSCB), enhanced service module (ESM), voice

processing module (VPM) and voice co-processing module (VCPM).

The MSR 50-40 routers are 3U in height and the MSR 50-60 are 4U in height. Slot 0 provided on the

front panel of both the two models is for the main control board, which can be MPUF or MPU-G2

respectively. MSCA or MSCB can be installed in the MSC slot provided on the backplane to provide a

variety of security and voice services, where MSCA works in conjunction with MPUF while MSCB works

with MPU-G2.

Base on power supply mode, the MSR 50-40 and MSR 50-60 each have three models: AC, DC, and PoE

power supply. You can choose to use a DC or AC power supply unit (PSU) as the system power supply,

or install two AC or two DC PSUs to form 1+1 redundancy backup. You can also install a PoE power

module to work in conjunction with the AC or DC PSU to provide remote power supply for powered

devices (PDs).

The PSUs, fan trays, and FICs of MSR 50 routers are all hot swappable.

Currently, the MSR 50 include these models:

• MSR 50-40

• MSR 50-60

NOTE:

• Boot ROM stores the Bootstrap for booting the router.

• Communication data between the system and the CPU is stored in the memory when the system is

running.

• The CF card is used to store the software system and configuration file. The CF card LED blinks when the

system is reading/writing data from/to the CF card. In this case, do not remove the CF card; otherwise

hardware and software damage may occur.

an MPU-G2 is applied on the router.

Generic Modules

The MSR 50 is available with generic modules such as SIC and FIC interface cards. For detailed

information about interface cards, refer to MSR Series Routers Interface Module Manual.

For the types of interface modules that each model of the MSR 50 routers can accommodate, refer to

Appendix A Interface Card and Interface Module Purchase Guide in the MSR Series Routers Interface

Module Manual.

Currently, the MSR 50 routers primarily support the main boards MPUF and MPU-G2. See details as

follows.

MPUF/MPU-G2

Functions

As the core of the router, the MPUF/MPU-G2 functions to process protocols, forward low-speed packets,

govern interfaces, and detect faults. You can gather information about the operating state of FAN module,

PSU, and system by reading their corresponding LEDs on the main control board; alternatively, you can

monitor state using a network management system. In addition, the main control board provides a

hardware reset button: RESET. Each MPUF provides four SIC slots for extending the access capabilities.

An MPU-G2 delivers improved process capabilities without offering any SIC slots.

• CF card functions as the major file storage medium to store application program files, anomaly

information, and configuration files.

• Boot ROM stores the Bootstrap for booting the router.

• Do not unplug the USB device during USB data transmission; otherwise, data loss or even hardware

failures may occur.

• The USB interface does not support hot-swapping of USB modems from Sierra Wireless.

4. Ethernet interface

The MPUF provides 10/100/1000 Mbps Ethernet interfaces that each accommodates an RJ-45

connector and a small form-factor pluggable (SFP) module respectively for electrical and optical

connections. But you can use only one connection at a time.

Five types of 1000Base-FX SFP transceiver modules are available: multi-mode short-haul (850 nm),

single-mode medium-haul (1310 nm), single-mode long-haul (1310 nm), single mode long-haul (1550 nm),

and single-mode ultra-long haul (1550 nm). They all provide LC interfaces and are hot swappable.

The attributes are listed in the following table:

NOTE:

The fiber-optic and electrical connections that a 10/100/1000 Mbps Ethernet interface provides canno

be used at the same time. If both connections are present, you can confi

ure which connection takes effec

through commands. By default, the electrical connection works.

5. Compact Flash (CF) slot

The MPUF provides one CF (PCMCIA) slot for a hot swappable CF card.

A CF card can store application programs, configuration files, and log information. With it, you can

conveniently perform such operations as online upgrade and log management.

CAUTION:

Do not remove a CF card during its read or write operation; otherwise, data loss and even hardware

damage will occur.

6. USB interface

MPUF provides two USB 1.1 interfaces: USB1 for Host and USB0 for Host and Slave that can be

configured. USB LED is valid only when USB0 is set to Slave.

NOTE:

• MSC (multi-service card) is installed in the slot provided on the backplane of the MSR 50 routers to carr

various service modules.

• MSCA is designed to work with MPUF while MSCB must be applied with MPU-G2.

ESM module

Installed on an MSC, ESM module supports IPSec and by using hardware encryption expedites IP packet

encryption. The use of hardware encryption/decryption and hashing operation allows the router to

encrypt packets with high performance and reliability.

The encryption card is optional. On a router installed with an encryption card, the main control board

functions to route IP packets and implement encryption-enabled VPN, while the encryption card functions

to encrypt packets.

Key algorithms: DES, 3DES, AES

Authentication algorithms: HMAC-MD5-96, HMAC-SHA-1-96

VPM and VCPM modules

VPM (Voice Processing Module) functions to coding/decoding, EC and CNG of voices.

VCPM (Voice Co-Processing Module) processes the voice data together with VPM.
