Input Modules
PM-HS-IB+/PT-HS-IB+: Digital Multirate Input Modules
Operation
Note: PM- series modules operate in 5RU and 9RU frames only. PT- series modules operate
in 5RU, 9RU, 15RU, and 28RU frames.
Figure 3-5 PM-HS-IB+/PT-HS-IB+ Module
The PM-HS-IB+/PT-HS-IB+ digital multirate input module receives any AC-coupled digital
signal with amplitude not exceeding 880 mV from 3 Mb/s to 2.97 Gb/s terminated with
75. The module automatically compensates the cable loss if the cable length is within the
assigned limitation. The equalized output is split into two identical data streams and fed to
the MI module via a module edge connector. If the amplitude of the input data is smaller
than the limitation (i.e., the cable is longer than the limitation), the output of the equalizer
will be muted and no data will be fed to the MI module. The equalizer function may be
bypassed if EQ is not desired.
The PM-HS-IB+/PT-HS-IB+ has the capability to support a variety of optional submodules.
Back Panel I/O Modules for PM-HS-IB+/PT-HS-IB+
The PT-V-BP back panel I/O module corresponds to the PM-HS-IB+ and the PT-HS-IB+
modules.
Submodules
The PT-DMX-3G/PT-DMX submodule module corresponds to the PM-HS-IB+ and the
PT-HS-IB+ modules. See page 134 for more information.
Note: Modules marked as PM-HS-IB+DX are PM-HS-IB+ modules equipped with
PT-DMX-3G/PT-DMX submodules. Modules marked as PT-HS-IB+DX are PT-HS-IB+ modules
equipped with PT-DMX-3G/PT-DMX submodules.
