Configuration Guidelines and Considerations
The first step in planning the configuration sequence of ASMi-54C modules is to
select the Transmission Convergence (TC) layer to be used by the module, HDLC
or 64/65 octet encapsulation:
• 64/65 octet encapsulation: supports only packet traffic, that is, only Ethernet
services. Each SHDSL line then operates alone (2-wires mode only), but the
total bandwidth available for an Ethernet port can be increased by bonding
together several lines, using the PAF (PME Aggregation Function).
For ASMi-54C modules, PAF can combine two or four lines for serving a single
PCS. The PCS can be connected by a flow to an Ethernet port (with four lines
per PCS, two PCSs can be configured, one for each ASMi-54C Ethernet port).
• HDLC encapsulation. To increase available bandwidth, it is possible to bond
together two or four lines (4-wires and 8-wires mode, respectively). Thus,
the maximum bandwidth for Ethernet services is obtained by configuring two
8-wires lines.
After selecting the TC layer, it is necessary to select the bandwidth, considering
the required range (see range data in
Chapter 1 ). When range is significant, it is
recommended to consider the use of multiple lines: this can yield the same
throughput as a single line, but because a lower rate per line is used, thus
increasing the range and reducing the effects of interference and crosstalk.
After determining the general planning parameters, other configuration
parameters can be selected in accordance with the specific application
requirements.
3.4 Including an ASMi-54C in LRS-102 Database
³ To program an ASMi-54C module in the LRS-102 database:
1. Navigate to the Configuration > System > Card Type screen.
2. Bring the cursor to the field of the prescribed I/O slot by clicking <Tab>, and
select ASMi54C.
3. Update the LRS-102 database, to save the new selection (type %, and then
type y to confirm).
If the programmed module is not yet installed in the LRS-102, it is normal to get
a warning message reporting a programmed/installed module mismatch.
