Building TTY's on an SMG

[dogg1]

Hi All,

we are starting to place s few SMG's out in the field which will hang off a CS1000E. I need to build a few TTY's at the SMG sites. The SMG's have a MGC Card with a CPDC card for a CP and SS. Do you build the local TTY's on the MGC and CPDC card? How many TTY's per card? Any info would be greatly appreciated

Thanks in advance!!

You build the TTY's just like any other MGC card at the local site. The local TTY's on the CPDC card will act just like the main site. The database is replicated over the WAN, or should be and the IP addresses are masked during the database transfer so the SMG has it's own separate IP address.

Thanks for the information KCFLHRC. Just a little more clarification. I can build my TTY's locally on the CPDC and MGC Cards. When the main site(CS1000E) replicates to the smg won't it complain about the differences in the tty's? Just curious. Still trying to understand that part of the SMG. I have built out 5 SMG's and one is in production.

Thanks for your help!!

No, the database is the same and is replicated to both Call Servers. You load the software on the main and the SMG and then program the replication schedule. The SMG runs independent and you can access it locally, it will be in an inactive state until the MGC's register to it. You need to look at NN43001-507_05.02_System_Redundancy_Fundamentals.pdf and look specifically at
