Setting Line Coding Framing Echo Cancellation Coverage (ms) Input Gain (dB) Output Attenuation (dB) Channel Configuration Channel Range Connection Settings Description Select the line coding from one of the following: • Binary 8-zero substitution (B8ZS) • Alternate mark inversion (AMI) Select the multiframe format of the span from one of the following: • Extended Superframe Format (ESF) • Superframe Format (SF) Select whether to enable or disable echo cancellation. If an issue occurs with echo cancellation, select a value to address the issue. Choose one of the following values: • 24 • 32 • 48 • 64 • 128 (available with MCS7890C1 internal gateway only) Note This option is available only if echo cancellation is enabled. This allows you to change the amplitude of the voice signal coming into the gateway created by adjusting the decibel (dB) level of the signal. You can increase the volume of a signal coming into the gateway by either increasing input gain or decreasing attenuation. You can decrease the volume of the incoming signal by either decreasing the input gain value or increasing the output attenuation. The minimum value is -6, and the maximum value is 14. Attenuation is measured in decibels, and the lower the number, the better the voice quality. Adjust the attenuation and input gain values to achieve maximum voice quality. The minimum value is -6, and the maximum value is 14. Specifies the channel range available for TI CAS connection type. Enter channels with dashes to specify ranges and commas to separate values, for example, 1-5,7,12. A maximum of 24 channels can be configured.
