Audio mode provides a high-quality audio (CD quality) interface. Audio mode supports the following features: One or two simultaneous channels. Codec sampling rates up to 48 KHz. Optional μ-law encoding and decoding. Embedded frame requiring no additional bandwidth. Copyright © 2018, Juniper Networks, Inc.

Page 13: Tdc Mode
This process is called adaptive time domain processing (ATDP). ATDP provides rapid convergence to the correct clock, and does not vary due to changes in the average jitter buffer fill. As a result, Copyright © 2018, Juniper Networks, Inc.
Page 14: Determining Optimal Packet Size For Ctp Bundles Overview
Bandwidth for Transporting Serial Data When considering bandwidth in relation to deciding packet size, add overhead for both the Layer 2 encapsulation and the IP header. The IP header comprises 20 bytes; and the Copyright © 2018, Juniper Networks, Inc.
Page 15: Packet Creation Delay
For example, smaller packets result in a greater packet rate. When you configure the packet size, consider the packet-forwarding performance of the attached router and network. Table 4 on page 10 provides examples of packet rates for various packet sizes and serial interface rates. Copyright © 2018, Juniper Networks, Inc.

Page 18: Transparent Encoding Overview
Clocks must disappear (transitions stop) periodically during circuit operation. The transparent encoding scheme is supported only when you have worked with the Juniper Networks Technical Assistance Center (JTAC) to verify that your application requires this encoding scheme. You may need to use special adapters on the cable to properly map the data and clock signals to the connector pins that the application uses.
Page 19: How Basic Transparent Encoding Works
This allows signals to be sent from additional interfaces that were not supported in Transparent 4 encoding, although the bandwidth usage will be higher. Copyright © 2018, Juniper Networks, Inc.
Page 20: Using Phase-Correction Fifo Buffer With Transparent Encoding
The data enters the FIFO buffer in phase with the clock passing through the network from the DTE to the DCE, while data is clocked out of the FIFO buffer with the clock that entered the network from the DCE, which is in phase with the user clock. Copyright © 2018, Juniper Networks, Inc.

Page 23: Tdm/Tdc Encoding Overview
When TDM is not being used, all 32 bits in the IP data stream transport serial data on a port. For example, Figure 8 on page 18 shows all 32 bits being allocated to local serial port data as indicated with the D. Copyright © 2018, Juniper Networks, Inc.

RT and RD outputs. The direct interleaving of two bundles’ data allows TDC to be maintained between the two bundles with an accuracy of one bit time at the bundle’s data rate. Copyright © 2018, Juniper Networks, Inc.
Page 25: Tdm Rates
If the ratio of circuit speeds is higher than 8:1, then you can use lower TDM rates, which allocates fewer bits for the TDM function and therefore uses less network bandwidth. Figure 13 on page 20 shows other supported TDM rates as applied to TDC. Copyright © 2018, Juniper Networks, Inc.
Page 26: Tdm High-Speed And Low-Speed Ports
The low-speed bundle is configured on an odd-numbered port that is one port number higher (N+1) than the high-speed port. It is configured for TDM/TDC clocking because it routes clock and data signals. Figure 14 on page 21 shows a high-speed port and low-speed port. Copyright © 2018, Juniper Networks, Inc.
