VII.3.E. EX200 (1E1/0) PRI /R2 /QSIG SWITCHABLE
E1 LINE MODULE
The EX200 (1E1/0) module does not have a line connection card however it has an MDF
cable with an RJ45-type male connector at the end. In addition to the common circuits
mentioned above, there is only a single E1 line (with 30 channels) on the module.
Connection to that line is fulfilled directly through the RJ45 connector, which is at the end of
the MDF cable.
Since PRI, R2 and QSIG are digital protocols, no extra circuit is needed; however, the
protocols are embedded on the microcontroller of the card and the selection among them is
made by programming (no hardware modification required). If R2 is selected the DSP
module present on the card generates or detects the MFC signals, which are specific to the
R2 protocol, simultaneously for 30 channels.
Since E1 has 30 speech channels, the 16 PCM frames in each slot do not suffice for the 30
channels of a line. Therefore, the EX200B (1E1/0) card should be installed in a slot with an
even number (the leftmost general-purpose slot has been numbered as 0) and the next slot
with an odd number should be left vacant. By this way, the EX200B (1E1/0) card can make
use of the 32 PCM frames in total, which belong to both of the slots.
In addition to the RJ45 socket, there is a 9-pin, D-type connector on the EX200B (1E1/0)
card, which is for the connection to the E1 line.
VII.3.F. EX200 (1CAS3B/0) CAS3B DIGITAL LINE
MODULE
The EX200 (1CAS3B/0) module has no line connection card, but it has an MDF cable with an
RJ45-type male connector at the end. In addition to the circuits that are common with the
other expansion cards, there are circuit components on the module that provides the
interface with the 30 digital lines. Connection to the CAS3B line with 30 channels is fulfilled
directly through the RJ45 connector that is at the end of the MDF cable.
The EX200 (1CAS3B/0) module has an E1-based structure. It provides high speed and
quality in network applications. Thanks to the DSP module present on it, it generates or
detects the MFC signals, which is specific to the R1 protocol, simultaneously for 30 channels.
Since the EX200 (1CAS3B/0) module can be connected to 30 separate channels, the 16
PCM frames in each slot do not suffice. Considering this fact, the EX200B (1CAS3B/0) card
should be installed in a slot with an even number (the leftmost general-purpose slot has been
numbered as 0) and the next slot with an odd number should be left vacant. By this way, the
EX200B (1CAS3B/0) card can make use of the 32 PCM frames in total, which belong to both
of the slots.
