Creating a TDM Gateway Service
This topic describes how to configure TDM gateway voice service (to a Calix C7 voice
gateway) on E-Series VDSL2 POTS ports. The TDM gateway solution employs VoIP
between the E-Series POTS ports and the C7 voice gateway, which converts voice traffic
back to TDM format for exchange on the PSTN. Each VDSL2 card or service unit can only
support one voice service type (TDM gateway, SIP, or H.248 gateway).
Use the VoIP Port Provisioning screen to activate VoIP ports and apply the following
previously-created profiles:
ï‚Ÿ TDM gateway profile
ï‚Ÿ TDM gateway service group (optional)
Use the same screen to disable Voice ports.
Note: For TDM gateway services, you can use the C7 gateway's internal DHCP server to
provide IP addresses for the VoIP hosts (recommended), or use an external DHCP server
option (requires Option 43 parameters included in the DHCP Offer).
Note: For instructions to configure the C7 TDM voice gateway, refer to the Calix C7 VoIP
Services Guide.
Profiles referenced in service provisioning
When provisioning subscriber services on a VDSL2 Voice port, you set up information that
is common to multiple subscribers and maintained in profiles. Repeating the similar task of
subscriber service activation then consists of referencing the existing profiles and sometimes
providing subscriber-specific information to complement the profiles.
Note: When a profile is changed, all subscribers using that profile are affected. Profiles
cannot be deleted while they are in use. Profiles can also be reloaded for a specific VDSL2
Voice port from the Service Table by clicking Refresh.
Voice Service IP Host
Although an IP Host is configured for voice services on a VDSL2 card, it is not explicitly
referenced when creating a voice service because it applies to all voice services provisioned
on the VDSL2 card. However, you are given the option to modify the existing IP Host or
replace it with a new IP Host definition, when provisioning the voice service.
TDM Gateway Service Report in CMS
CMS allows you to run a database search for provisioned TDM Gateway services on a multi-
platform basis, and then generate a report on the results.
