The E1 module is one of the most common choices for audio transport due to the reliability and wide availability of the T1 and E1 circuits.
The main advantages are:
Line Redundancy – Each module consists of two T1/E1 frame devices and two line interfaces enabling line redundancy.
Drop & Insert – The E1 module provides a fail-safe circuit that, in the event of total module failure, connects the upstream E1 circuit to the downstream E1 circuit, thus preserving the integrity of the data path to any other device on the network ring.
Data and Clock Contribution – Any data received on the X.21 port is placed on the T1/E1 transport link. Combined with the external clock input, this module provides versatile system timing options to connect to almost any network.
With a modular, single-platform approach, multiple layers of redundancy and exceptional scalability and flexibility, the APT E1/ MULTI-CHANNEL CODEC is the perfect solution for studio-to-transmitter links, studio-to-studio links, remote broadcast, backhaul and studio link applications.
