An Overview of Features in 10.1 (Initial Release)
The following features were included in the initial release of the IMG 1010 (Release 10.1):
Telephony Interfaces
28 T1
21 E1 120 Ohm
IP Interfaces
2 Fast Ethernet for Gate Control EMS
2 Fast Ethernet for VoIP Signaling
2 GIG-E for IP Bearer Traffic
VoIP
The IMG supports two VoIP modules, each supporting the following features:
384 VoIP resources
Codecs: G.711, G.723.1, G.729
G3 Fax Relay that is compliant with the T.38 ASN.1 standard.
Voice/Fax/Data: Automatic Switching
Fax Support: Group 3 2.4 – 14.4 kbps, T.38 compliant fax relay or automatic switch to PCM
Modem Support: Up to V.92 rates, automatic switch to PCM
Echo Cancellation: G.168-2000 Compliant; Maximum tail length of 64 milliseconds.
Ping and Trace Route Capabilities
If the IMG has two VoIP modules in it, the software will automatically spread all the licenses evenly across the two modules. This process is done in groups of 32 channels, so if there is an odd number of blocks, module 0 will have the extra channels.
