Abstract
A network termination module for telephone network interface apparatus is provided with a selectively operable latching device for a lock securing the security cover over the subscriber terminals. With the latching device in a position to engage the security cover lock, the cover can be opened only by keying open the lock and removing it. On the other hand, an authorized person can, upon opening the telco cover of the apparatus, expose the latching device whereby it can be displaced to enable opening of the security cover without unlocking or removing the lock.
