How do we check the Ericsson B-Table? Like what are the main parameters to be validated.
How are the Routing Table and EOS Table related to one another
cheers
felixB table will have the RC (Routing case), modifications (if any), charging case (for CDR generation), number type.
Routing case will specify which route call has to be routed.
what is B-table ? is routing protocol ?
It is not a protocol. It is a table containing the b numbers & the route where they should be routed to. When a call is made, the exchange would like into the B table. If the number is available, it would take the route & connect your call.
is it present in the HLR or MSC
thks
It is in the MSC.
how then the EOS table play role in the call routing in ericsson
thks
The B-Table include all the numbering plane that the subscriber will call as example if the subscriber call 00201112853 an Egypt number (international) so first its will inserted in the b-number to analyze this number to route it to the correct route( the route include traffic time slots).
The relation between the b-table and the EOS is that an example if the b number was no in the b-table the EOS code will be generated and will be analyzed also in EOS table to generate the correct announcement
B number table for Ericsson like MOTOROLA Trnaslation.However,B number table have RC to HLR for Own PLMN and than Selection for MSC(If More MSC in that PLMN).Otherwise call will go to POI defined with taht MSC or another MSC.
Before B-Number table,MSC analyzing the Pre analysis,number taken from A number.by PNBSP you can see the pre analysis table.Are there any wild characters which will be defined in the B Table for having bifurcation for incoming/outgoing or Prepaid/Postpaid like that.
cheers
scorHi Scor. What did you mean? Give us a traffic case sample.
For printing existing B-number table on Ericsson MSC, you execute
ANBSP command,
Which will have data in format
oba-bnumberdigits M-XYZZY RC CC
In Eric system, prepaid & postpaid calls are routed seperately (Seperate origin in other words).
Prepaid calls are prefixed with a trigger (IN).
When a call can not be routed / announcement has to be played then it is sent to EOS (End of Selection). EOS can be used for other purposes as well.
Hope it clarifies
B-number analysis is almost the first analysis to be carried out in call setup
