Hi everybody,
I have faced the following problem.
We have 2 servers: Server1 (with working service based on Global Call) and Server2 (which is a test server).
Both of them have SPCI4 cards with E1 cables plugged and which connect them to mobile operators MSC.
Server1 is already configured (by outsourcing company which delivered the mentioned service solution).
Server2 is configured but is not working yet, and I am trying to configure it based on the Server1's configuration.
The problem is that the Server2 and MSC can't see each other.
Here is the MSC configuration for the Server1 (which is OK):
SPCI4 Card SP=2-4038
MSC SP=2-4000 and 2-4001
CIC1 =33, CIC31=63
Here is the MSC configuration for the Server2 (which is not OK):
SPCI4 Card SP=3-3987
MSC SP=3-4000
SLC=0 on TS1 (CIC1)
CIC2=2, CIC31=31
At the moment we need to make so the both MSC and Server2 are up and available.
That's why I have removed all the ISUP level configuration commands from Server2's config.txt file.
In addition, I made an E1 crossover cable, plugged it to 3rd and 4th ports on Server2's SPCI and set up an MTP for loopback test.
Loopback test worked just fined.
I used the following commands to start gctload and bring up mtp links.
C:\septel>gctload -d
C:\septel>mtpsl act 2 0 * 3rd port
C:\septel>mtpsl act 3 0 * 4th port
C:\septel>mtpsl act 0 0 * 1st port which is connected to MSC
You can see from the logs that 3rd and 4th mtp links are up, but 1st gives "OUT OF SERVICE" message.
By the way, there are many "FRAME SLIP" and "BER5 OCCURED" messages in the log of Server2.
Please, guys, I need your advice.
Mobile Operator says that this is a Point Code missconfiguration on Server2.
But I have intentionally corrupted Server1's config.txt (changed Network Identifier from 2 to 3 [SSF value 0x8 -> 0xc] and I saw that I really couldn't get "Destionation available" message, but I do get "IN SERVICE" message, while on Server2 I only get "OUT OF SERVICE" message.
This makes me think that the problem is elsewhere, probably on a physical level.
Thank you

Just wanted to clarify the last statement.
I meant that I have intentionally put the wrong SSF value of 3 (instead of the correct one 2) and tried to start gctload and I got the following statements:
S7L:I0000 Level 2 State : id=0 INITIAL ALIGNMENT
S7L:I0000 Level 2 State : id=0 ALIGNED READY
S7L:I0000 Level 2 State : id=0 IN SERVICE
and I didn't get any MTP event and "Destination available" message.
I mean, if it were the problem with the Point Code misconfiguration then I would receive that kind of stuff. But the only messages I get are "OUT OF SERVICE".
Probably the real problem is with physical connection or I have issues with wrong clocking settings.
Please, help. Thanks in advance.
The problem is solved.
As expected, Mobile Operator guys made a mistake in their configuration.
