Connection Settings Setting Protocol Side Clock PCM Type Line Coding Framing Echo Cancellation Coverage (ms) Description This setting specifies whether the gateway connects to a Network device or to a User device. Make sure that the two ends of the PRI connection use opposite settings. For example, if you connect to a PBX and the PBX uses User as its protocol side, select Network for this device. Typically, use User for this option for central office connections. Select Internal or External for the clock source. Specify the digital encoding format. Select one of the following formats: • a-law-Use for Europe and other countries, except North America, Hong Kong, Taiwan, and Japan • mu-law-Use for North America, Hong Kong, Taiwan, and Japan Select the line coding from one of the following: • High Density Bi-polar 3 (HDB3) • Alternate mark inversion (AMI) Select the multiframe format of the span from one of the following: • Cyclic Redundancy Check 4 (CRC4) • Non Cyclic Redundancy Check 4 (NonCRC4) 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.
