Sonus SBC-1K-LIC-T1E1 1 T1/E1 Port

Activate one T1/E1 port on the SBC 1000 with a license designed for exact interface expansion. SBC-1K-LIC-T1E1 gives infrastructure teams a direct way to add a legacy voice connection point while keeping the existing session border platform in place. This type of entitlement is valuable when a deployment must bridge older TDM-based connectivity with current SBC architecture. Rather than replacing the system or overprovisioning unused ports, the license lets teams add only the interface they need. That keeps capacity planning tight and avoids unnecessary hardware changes. For organizations maintaining mixed voice environments, the result is cleaner integration and more predictable expansion. It is a practical licensing choice for controlled upgrades, migration projects, and environments where T1/E1 connectivity remains part of the operational requirement.
