Benefit

Value-for –Money Solution
eSPG provide single solution to reduce ongoing operational and management costs.

High Quality Performance
No interference with xDSL or other broadband services in near pair.

Powerful Network Management
Simplified network management system reduces daily operation and maintenance costs

Safety Design to Prevent Damage
Over-current, over-voltage protection design without sacrificing performance and reliability.

Low Voltage Power-up Safety Function
High voltage to the Digital line is connected only after the exchange unit has sense current signature from remote unit signature.
