Chapter 1 Overview

1.1 General Description

MA5105, one of the MA5100 Multi-service Access Module (including MA5100, MA5103

and MA5105) developed by Huawei Technologies, is a cassette mini-DSLAM

broadband access device. It supports ADSL service, SHDSL service, hybrid ADSL and

SHDSL service. MA5105 can be added in the ONU node to provide broadband

services. MA5105 provides three kinds of upstream interfaces: FE, E1 ATM UNI and

IMA, therefore it can be used either as IP-DSLAM equipment or as ATM -DSLAM

equipment.

Dimensions of MA5105 are 44.45×436.00×400.00mm (H×W×D). MA5105 is compact

and designed for installation in a standard 19-inch rack or on a desktop. It has three

slots, with two for service boards and one for upstream boards. MA5105 supports -48V

DC power supply and 220V/110V AC power supply. It uses fans for air cooling and air

conduits at both sides guarantee good ventilation.

MA5105 provides standard interfaces which are highly compatible to ensure

interworking capability. In coordination with upper layer equipment, MA5105 provides

user management and service supporting, thus implementing network operability and

manageability.

1.2 Network Position

MA5105 is located at the edge of access layer. With multiple upstream interfaces, it

takes full advantage of existing network resources and decreases the networking cost.

Via FE upstream interfaces, MA5105 can be connected with L2/L3 switch to function as

IP-DSLAM. Alternatively, MA5105 can function as IP-DSLAM or SHDSL-DSLAM

through E1 upstream interface and SDH transmission equipment in the access network.

MA5105 provides IMA interface as well, through which ATM cell stream are transmitted

over multiple E1 links. MA5105 enables network manageability and operability, in that it

implements such functions as service distribution, user management, network security,

authentication and accounting through networking with other devices by Huawei

Technologies.

Chapter 3 Networking Applications

3.1 Functions

3.1.1 Supporting ADSL Service

ADSL technology transmits high-speed data over existing phone lines. As the ADSL

frequency band is separated from that of POTS service, ADSL services won’t disturb

the voice services. In coordination with ATU-R through twisted pair, MA5105 provides

ADSL services in a cost-effective way, including Internet services, VOD, distant

learning etc.

3.1.2 Supporting SHDSL Service

SHDSL uses TC-PAM line code modulation / demodulation, and delivers symmetric

transmission rate at 192kbit/s~2300kbit/s for two lines. The line rates can be adjusted

according to the line condition at the step of 8kbit/s.

In coordination with SHDSL transceiver unit at the remote end (STU -R), MA5105

provides SHDSL dedicated services in ATM mode. It provides high-speed symmetric

dedicated services for small-/medium-sized enterprises who cannot afford private

network or DDN cost and SOHO subscribers. It guarantees network security by means

of QoS.

3.1.3 Providing FE Upstream Interfaces

When FE interface serves as the upstream interface, MA5105 can be directly accessed

into IP MAN to enable IP -DSLAM solution. In IP -DSLAM application, ATM cells are

terminated in MA5105, and converted to Ethernet frames.

FE interface supports suppression on downstream broadcast packets & unknown

unicast packet. It supports IEEE802.3x traffic control and 802.1p Ethernet priority.

Flows can be bundled based on PVC+IP address +MAC address. This function can be

enabled or disabled on each PVC.

3.1.4 Providing E1 Upstream Interfaces

When E1 ATM UNI interface servers as the upstream interface, MA5105 can be

connected with E1 interface of the upper layer equipment, such as Huawei MD5500 or


3-2

MA5105 over the existing the SDH transmission resources. Further more, it can access

the ATM network. In upstream direction, it adapts the cells of various PVCs to one E1

link. In downstream direction, it extracts ATM cells in E1 port, and distributes them to

various ADSL ports in compliance with ITU-T Recommendation G.804. Traffic buffering

is available on PVC basis in both upstream and downstream directions.

3.1.5 Providing IMA Upstream Interfaces

When IMA servers as the upstream interface, MA5105 supports ATM broadband

services over conventional narrowband network through the E1 lines. In upstream

direction, ATM cell stream is multiplexed over multiple E1 links, and the original stream

is retrieved in the downstream direction from the E1 links.

When APCA, which is a subboard supporting flow control, is configured in MIMA,

MA5105 supports different types of services, including CBR, rt-VBR, nrt-VBR and UBR

service. Flow control and service priority is enabled as well. Without APCA, MA5105

supports UBR service and service priority..

3.2 Networking Applications

In actual networking, MA5105 is in the position of ONU. It can network with other

devices by Huawei Technologies, such as MA5100, MA5200E/F, MD5500, Metro, L3

switch or routers, or devices by other manufacturers to implement small-capacity

ATM-DSLAM application and IP-DSLAM application. The typical networking model is

as shown in Figure 3-1.
