Add a Media Gateway
Task Check list:
|1.||Add an MGC Superloop||2.||Configure the hardware||3.||Add the TLAN addresses|
|4.||Add the VGW (DSP)
|5.||Add the Digitone Receivers
|6.||Add Conference and Tone
You will need to know:
- The sites IP scheme and Gateway address & zone
- Common Equipment data, printed in LD 22: PRT, CEQU
- Installed media gateways, printed in LD 117: PRT IPMG
Steps in detail:
1Define a new Media Gateway (MGC) in LD 97 (can also be achieved in Element Manager):
REQ CHG CHG or PRT the SUPL data block TYPE SUPL SUPL 0 we will define superloop 0 SLOT SUPT IPMG superloop type is an IP Media Gateway IPR0 10.11.1.52 ELAN address for shelf 0, MGC must be set to this address IPMG_TYP0 MGC type = (MGC), MGX, or MGS) ZONE0 1 never use zone 0, zone intent must be MO for Media Gateways **** ALL VWG CHANNELS MUST BE OUTED AND RECONFIGURED AFTER IPMG ZONE CHANGE DES0 enter through this section... -CE -1E -E -CT -2T -T IPR1 10.11.1.53 hit enter if not applicable, otherwise continue with shelf 1 IPMG_TYP1 MGC if MGC, this is an additional card, if MGX, this is the RHS ZONE1 1 **** ALL VWG CHANNELS MUST BE OUTED AND RECONFIGURED AFTER IPMG ZONE CHANGE DES1 -CE -1E -E -CT -2T -T WRAP UP SUPL 004 ..OK RESTART IPMG 000 0 / 000 1 TO ALLOW CHANGES TO TAKE EFFECT.
2Configure the MGC and Gateway hardware:
- The MGC must be fitted with DSP daughter boards.
- The Media Gateway, and Call Server IP addresses must be set in the MGC.
NOTE: Access to Element Manager is necessary to complete the TLAN and DSP (VGW) IP configuration. Element Manager stores the full MGC configuration in
mgcdb.xml which is then transfered to the card (via SFTP) upon ELAN registration.
3Configure the remaining IP addresses in Element Manager:
- Configure the ELAN Gateway and Subnet mask
- Configure the TLAN IP addresses (shown in red).
Note, the TLAN Sub-mask defaults to .253 - this must probably be changed.
- Configure the DSP IP address(s) for the DSP hardware fitted (shown in red).
Select the DSP daughter board size form the drop down box.
4Configure the VGW Channels:
From the IP address page, click VGW Channels.
Build VGW's on appropriate card slots to match the hardware:
➤ DB1 - card slot 11 (12, 13, and 14 for 128 port DSP's).
Always start at TN 0-0-0-1, sacrificing unit 1 on slot 0.
5Configure the Digitone Receivers:
This can also be done in LD 13:
REQ: new 8, TYPE: dtr, TN l s c u
Print DTR's in LD 20, STAT them in LD 32.
See MGC DSP daughterboards for more detail.
Don't forget the Digitone Receivers! Sets and tie-trunks will not be able to break dial-tone without them!
CONF Loop 101, 102, etc.
TDS Loop 151, 152, etc.
Enter down to - MGTDS / MGCONF and add a new loop.
Enter IPMG (IP Media Gateway) loop and shelf when prompted.
Every MGC needs Conference and TDS loops, don't forget them!
Print the STATus in LD 38 (MGCONF) and LD 34 (MGTDS).
Media Gateway Status:
Make sure the network connections are linked-up, the following messages should display:
ELAN014 ELAN 0 host IP=10.11.1.52 is enabled SRPT226 Registration has been granted for IP[10.11.1.52] IPMG[0 0]
From Release 7.5, Media Gateways must register with both Call Server and Secure Domain. To register an MGC with the Secure Domain (if applicable), use the LD 117 command:
reg ucm dev <ip-address>. See Check Registered Elements.
➤ MGC (Call Server) status is displayed in LD 117:
=> stat ipmg LAST REG LAST REG IPMG TYPE STATUS DATE TIME UPTIME 000 0 MGC REG 28/10/2013 17:27 0d,0h,1m 000 1 MGC REG 28/10/2013 17:27 0d,0h,1m
➤ MGC type, ELAN IP address, and zone can be printed in LD 117:
=> prt ipmg IPMG IP Address Zone Type 000 0 10.11.1.52 1 MGC 000 1 10.11.1.53 1 MGC
DSP daughterboard status information is accessible from the CLI with Load 32.
The following example reflects a 32 port DSP in the DB2 position, no DSP in DB1, and 8 DTR's.
REQ: stat 0 0 0 00 = UNIT 00 = UNEQ This TN 0 0 0 0 is invalid, and must be unequipped 01 = UNIT 01 = IDLE (TRK)(IPTN REG ) 02 = UNIT 02 = IDLE (TRK)(IPTN REG ) : 31 = UNIT 31 = IDLE (TRK)(IPTN REG ) - registered and idle REQ: stat 0 0 11 CARD 11 UNEQ CARD 12 UNEQ CARD 13 UNEQ REQ: stat 0 0 15 00 = IDLE (DTR) 01 = IDLE (DTR) 02 = IDLE (DTR) 03 = IDLE (DTR) 04 = IDLE (DTR) 05 = IDLE (DTR) 06 = IDLE (DTR) 07 = IDLE (DTR)
If the MGC is off-line, or there's a configuration mismatch, the DSP's will be disabled and unregistered:
REQ: stat 0 0 0 00 = UNIT 00 = UNEQ 01 = UNIT 01 = DSBL (TRK)(IPTN UNREG ) - unregistered and disabled 02 = UNIT 02 = DSBL (TRK)(IPTN UNREG ) :
