XP-DSM Network Conﬁ guration Quick Start Guide

The following instructions cover basic network conﬁ guration for operation of the XP-DSM using a single IP address.

Additional information is available in the XP-DSM Technical Manual available at www.alpha.com.

To prepare your network to read incoming data from ﬁ eld installed XP-DSMs, complete the following steps:

Step 1: Prepare a DOCSIS Conﬁ guration File

Prepare a type-length-value conﬁ guration ﬁ le for the cable modem. The ﬁ le should include the modem’s community

strings settings. If a DSM Setup File is going to be used to distribute transponder settings (see step 5), then the

parameter docsDevSwServer

must be set in the DOCSIS

Conﬁ guration File with the IP

address of the TFTP server

on which the DSM Setup File

is saved. This entry may be

deﬁ ned as either type 21 or

type 11.

Sets Read-Write Community

string. Set the IP addresses

and community strings to ﬁ t

your system.

Sets Read-Only Community

string. Set the IP addresses

and community strings to ﬁ t

your system.

Step 4: Compile the MIB ﬁ les on the SNMP Management Server

Download the Alpha MIB (ATI-TABLES-MGMT-MIB) from www.alpha.com; type XP-DSM in the search box to bring

up the ﬁ le. The Alpha MIB is used to set DSM speciﬁ c settings. The SCTE-HMS MIB ﬁ les are required for the

SNMP management server to collect data from the transponders. The ﬁ les are available on the Society of Cable

Telecommunications (SCTE) Web site (www.scte.org). They must be compiled in the following order: SCTE-ROOT, SCTE-

HMS-ROOTS, SCTE-HMS-PROPERTY-MIB, SCTE-HMS-ALARMS-MIB, SCTE-HMS-PS-MIB, SCTE-HMS-GEN-MIB.

Step 5: Set Communication Options

There are three ways to set the XP-DSM communication options: using SNMP in a MIB Browser, using the Local port, and

using a DSM Setup File. Before proceeding, verify UDP ports 161, 162, and TCP port 80 are not blocked.

The XP-DSM will inherit the cable modem community string settings provided by the DOCSIS conﬁ guration ﬁ le. If the

cable modem is left unsecured, the XP-DSM uses the default community strings AlphaSet and AlphaGet.

NOTE:

Step 2: Provision the DHCP Server with the XP-DSM's RF MAC Address

On the DHCP Server, assign the RF MAC Address the DOCSIS Conﬁ guration File created in Step 1. The RF MAC

Address is located on front of the XP-DSM. The XP-DSM accepts either a static or dynamic IP address assignment.

Step 3: Install the XP-DSM Hardware

Refer to the XP-DSM Hardware Installation Quick Start or the XP-DSM Technical Manual, both available at

www.alpha.com.

See the XP-DSM Technical Manual available at www.alpha.com for complete Alpha MIB parameter deﬁ nitions.
