Configuring The Low-Speed Ctp Bundle For Tdm/Tdc Operation; (Ctpview) - Juniper CTP Series Manual

Table 25: High-Speed CTP Bundle Parameters for TDM/TDC Operation in CTPView
Field Function
Serial Specifies the serial encoding method used on this bundle.
Encoding
TDM Specifies the TDM function. Currently, only one TDM function
Function is supported.
This option is available only on even-numbered ports on a
CTP2000 serial module, and when the serial encoding
parameter is set to TDM.
TDM Rate Specifies the number of bits out of 32 that are used for the
TDM function (and not for local serial port data).
Keep in mind the following when you configure the TDM
rate:
If the rate is too low, the bundle may not carry the
low-speed data because of insufficient oversampling.
If the rate is too high, the low-speed circuit will still run,
but will likely use more bandwidth than necessary.
You may want to configure a higher rate to increase the
TDM rate to reduce jitter on the low-speed clock and data
signals.

In the table of bundles, select the bundle that you want to modify. You must configure
3.
the bundle on an even-numbered port.
Under Port Options, configure the parameters as described in
4.
and click Click to Submit Bundle AND Port Changes.
Configure the rest of the bundle as you normally would.
5.
Configure the low-speed bundle on an odd-numbered port that is one port higher than
the corresponding high-speed bundle.
Before you begin:
Log in to the CTPView software at least at the Net_Admin level.
Connect the CTPView server to the CTP device for which you want to configure bundles.

Your Action
Specify TDM as the encoding method.
Select the following:
TDC Clk/Data on port N+1—Oversamples the
incoming clock (TT) and data (SD) from the
adjacent port above this one (N+1) at this port's
clock rate, and embeds it in its data. At the remote
end of the network, the embedded circuit data is
recovered and exits the node on port N+1 as RT
and RD outputs.
Because of the direct interleaving of two ports'
data, TDC is maintained between these two ports
with an accuracy of one bit time at this port's data
rate.
