Why AXE 810?

Reduces cost of ownership:- maintenance/man-hour costs- less power/cooling- faster installations- more capacity- reduced site rental/purchase costs

Modernization & new interfaces- APG40 TCP/IP to O&M network- ATM link interface (AAL2)- ET155-1 STM1 SDH interface/ET4-1 for PDH accesses

What is AXE 810?

•AXE 810 is the name of AXE version which is available in the market

•AXE 810 is based on a new type of subrack called GEM

•AXE 810 hardware is updated toward a smaller footprint and larger capacity

Changes from BYB 501 to AXE 810

1. New GEM subrack – Houses GS and boards such as ET155, Houses GS and boards such as ET155, TRAR6 and Echo CancelersTRAR6 and Echo Cancelers

2. New GS – high capacity of max 512khigh capacity of max 512k

3. 1 board ET155 – helps to decrease size of switchhelps to decrease size of switch

4. New boards – TRAR6, RPG3, Echo CancelersTRAR6, RPG3, Echo Cancelers

• In each GEM magazine – 2 XDB boards exist (16K per pair)

therefore for a 512K group switch 32 x 16K = 512K

ET155 Tutorial

ET155 in AXE 810 is a single board which can be used to interface between MSC & BSC or to SDH (Telkom) and many other via optic fibre

Tutorial ET155

• A new board needs to be defined on DBBSC4 for RALT2 devices, this will interface to DBMSC3, with reference to your layout define this board

1. Position 4 & 15 to be used

2. SNT = ETM2-0

Question:

1.What do you do to see which ET155 has been affected?

2. How do you restore traffic asap if it has not switched to the protection?

Solution Maintenance

• Check if any dips have failed – DTSTP:DIP=ALL;

Where is the fault?

• Check optics from ET4 to ODF and to the ET155 board

HOW? Optic loops back to the ET155 card – TPSTP:SDIP=XXXX;

• ET155 board does not come up

Replace ET155 board

• Clear active lock - PWFSE:SDIP=XXXX;

Define GS pos for TRH upgrade

Additional GS position needs to be defined for the magazine
