1588V2

Two time synchronization solutions in MA5600T OLT get the time synch signal from 1588v2 server (e.g. Huawei T6020) through the 1pps+ToD interface, which time source is get from

GPS; End to end 1588v2. OLT get the time synch signal from upper network through standard 1588v2 mode, which is delivered node by node in

upper network;

Time synchronization process: MA5600T will deliver the time synch signal to MA5612/MA5628 through GPON synch mechanism after time synchronization; MA5612/MA5628 deliver the time synch signal to base station through 1588v2 or 1PPS+ToD time interface after retrieving time synch;

High Performance for Synchronization Solution

Clock accuracy can fully meet the requirement of frequency and time synchronization for 2G/3G/LTE.

1588V2 on GPON line, frequency jitter will be within 12ppb, and time error will be less than 100ns, all these data come from lab test.

Built-in Stratum-3 clock in MA5600T and ONU, hold the clock precision for 24 hours if input source is lost.

MA5600T system have two

VPN implementation

modes:

One is QinQ VLAN, in this mode,

OLT tag outer VLAN to identify

the enterprise belonging, which

is the same value within same

enterprise;

Another is ETH PW, in this

mode, OLT initialize MPLS LSP

to set up ETH PWE3 according

to the enterprise belonging and

service type;

Comment:

ONU can be MA5612/5628,

must not be ONT.

Scenario 2: Enterprise PBX Access

For traditional PBX access One application is E1 interface which

traffic can be delivered to OLT through

Native TDM Another is PRA/BRA interface which

protocol will be ended up and

transferred to H.248 or SIP calling by

ONU.

For IP PBX access Directly connect to ONU by FE interface,

then transparently transmit to OLT in

layer 2.

For DDN data network access A protocol converter can be used for

translation between V.24/V.35 and E1.

(Outsourcing, not from Huawei)

Comment: For ONU, Only MA5612 support PRA

interface, and one E1 card can support 2

PRA interfaces.

The Router/LSW in enterprise side can be

either Huawei or other standard equipment;

Forwarding mechanism: If two branches of same enterprise are under

same OLT, the OLT can enable forwarding

function between related ports based on same

VLAN value;

Else under different OLT, OLT can set up

leased line to realize forwarding each other by

QinQ VLAN or MPLS PW;

Scenario 5: Native TDM + TDM PWE3

Scenario description: MA5612/MA5628 access enterprise with TDM E1 interface, and access to MA5600T with Native TDM mode; MA5600T access to upper layer PSN network after encapsulating Native TDM to PWE3; MA5600T or CX600 terminates the PWE3 back to Native TDM to other part of the enterprise.

Clock solution description: OLT have two ways to get the clock source in this scenario: Synch Eth and BITS; OLT deliver the clock signal to ONU through GPON line clock, then ONU deliver clock to base station through synch eth or

specified clock interface; Advantage:

PW encapsulation is centralized in OLT, which simplify the ONU function and reduce the total CAPEX; High accuracy clock from BITS and synch eth can fully meet the base station requirement ;

Enterprise Access Solution Highlight -- HQ and Branch under the same OLT

Current Network Pain Point

: Based on the security consideration,

Normally, the user under one OLT is

isolated each other even with same

VLAN flag.

Solution : Forwarding between different ONU

under same PON port

Forwarding between different PON

port within same PON board

Forwarding between different PON

port belonging to different PON

board

All above are under same OLT

Comment: ONU can be MA5612/5628, must not

MSTP: Support MSTP/STP, the switching time: 1~2 second;

BFD/VRRP: switching time: less than 50ms;

RRPP: RRPP ring can ensure that the switching time will be less than 50ms;The switching time is not related with ring node number, but normally no more than 10 nodes;RRPP is Huawei proprietary protocol, so that all ring node equipment must be Huawei product;
