Note:R2 only supported on 64 E1/T1/J1 and 16 E1/T1/J1 mezzanines #### SS7 MTP2 Links From 1 to 64 links per TMG unit. Up to 256 SS7 links per system. #### SIGTRAN M3UA/M2PA/M2UA association * M3UA : From 1 to 20 associations, in step of 1 association, software upgradeable. * M2UA : From 1 to 64 associations, in step of 1 association, software upgradeable. * M2PA : From 1 to 64 associations, in step of 1 association, software upgradeable. ### VoIP Hardware upgrades, field upgradable. The TMG3200 have 4 VoIP mezzanine slots. We have four different VoIP mezzanine capacity available: * VoIP-1 equals 128 universal channels. * VoIP-2 equals 256 universal channels. * VoIP-3 equals 384 universal channels. * VoIP-4 equals 512 universal channels. Any mix of the different VoIP mezzanine is possible. We recommend the use of VoIP 4 to better protect the end-user investment (at least when using 32 E1 and more). --- # Agent Instructions This documentation is published with GitBook.
