IP•Tube V35 HDLC

Scenario: HDLC OVER IP
This sample configuration details the interconnection of a WAN Routers running Point to Point Protocol via IPTubeV35s that are providing smooth clocking at a rate of 128 Kilobits per second. The IPTube's Ethernet interconnection has a committed information rate that is much greater than the IPTube's maximum data rate. Therefore the Ethernet bandwidth available is relatively unlimited.
The Tube Clocks on one of the IPTubeV35s are both set to Internal. The SCRCLOCK will be set to run at the same speed as the SCTCLOCK without gapping. Buffering of packets is not required and the Frames Per Packet is set low minimize latency.
For this example, the user will select Frames-Per-Packet = 2. With this TUBE FPP setting, the Overhead Table in Chapter 6 indicates an approximate 34% (ratio is 1.34) overhead. IPTube Ethernet Data rate is 1.34 times 128Kbps which equals 171.52 Kilobits per second.
