1. A telecommunications device comprising:
- an error injector configured to;
determine that a data transition rate of a data stream exceeds a pre-specified rate; and
update operations of the error injector to inject symbol errors into the data stream prior to transmitting the data stream to a second telecommunications device to reduce transition frequencies in the data stream when transmitted to the second telecommunications device, wherein the injecting is performed in response to the determination that the data transition rate exceeds the pre-specified rate; and
a transmitter configured to transmit the data stream that includes the injected symbol errors to the second telecommunications device over a telecommunication line.

Abstract
Methods, systems, and apparatus for automatically injecting symbol errors into a data stream prior to transmitting the data stream for timing recovery robustness are disclosed. In one aspect, a first telecommunications device determines that a data transition rate of a data stream exceeds a pre-specified rate. In response to the determination that the data transition rate exceeds the pre-specified rate, the first telecommunications device injects symbol errors into the data stream prior to transmitting the data stream to a second telecommunications device. The pre-specified rate is based on at least a nominal passband of the second telecommunications device.
