1. SMC8511 Outdoor Cable Modem

Figure 1-1 SMC8511 Outdoor Cable Modem

The SMC8511 Outdoor Cable Modem allows CATV operators to offer commercial broadband IP data services to customers requiring a hardened DOCSIS 2.0 cable modem suitable for outdoor environments. Applications include traffic light controllers, security and traffic cameras and other outdoor devices requiring IP backhaul. The SMC8511 is pictured in Figure 1-1 mounted on a CATV strand. A flexible pipe mounting system is available as well. See Section 2 of this Manual

Mechanical Installation

Power may be provided to the SMC8511 Outdoor Cable Modem by one of two methods:

for details of the mounting assemblies.

• CATV 60-90 VAC (nominal) along with the RF through the F-Connector,

• Power over Ethernet (PoE)

In addition, when the SMC8511 Outdoor Cable Modem is powered from the CATV system through its F-connector interface, it can optionally port to power the external Ethernet device.

When the SMC8511 is to be CATV line powered the tap must be power passing and the attenuator value chosen to present the system standard levels to the internal cable modem. A surge protector (furnished) provides protection from system power events. The laptop computer utilized for configuration plugs into the Ethernet port.

Note: Do not exceed 28VDC into the power injector (no 48 VDC injectors), and do not use a power injector which places DC voltage on the data leads.

See Section 3.4 for connections.

When the SMC8511 Outdoor Cable Modem is powered by means of PoE the connections are given in Figure 3-3, below. When the SMC8511 Outdoor Cable Modem is powered by 60-90 VAC CATV system power it can optionally provide 24 VDC output to an attached Ethernet device. The connections for this application are also as given in Figure 3-3, below.

4.1 SMC8511 Business Class Outdoor Cable Modem

The simplified block diagram of the SMC8511 Outdoor Cable Modem is as shown in Figure 4-1. The SMC8511 includes a full-featured business class gateway DOCSIS modem.

In standard operation the internal DOCSIS 2.0 cable modem (CM) will obtain an IP address from the head end DHCP server via the normal CM registration process as required by the particular CATV system. Once the cable modem completes its registration process with the DOCSIS head end, the DHCP client function in the external Ethernet connected device will also obtain its IP address from the DOCSIS head end DHCP.

5. SMC8511 Business Class DOCSIS Outdoor Cable Modem

5.1 Features

• Designed for commercial high speed Internet customers

• Integrated DOCSIS 2.0 cable modem

• One block of globally routable static IPs assigned to public LAN interface

• Static IP and block of public LAN IPs enabled via RIPv1/2

• Alternatively supports static IPs with static routes

• Remote management via CLI (TELNET), SNMP (DOCSIS defined and proprietary MIBs),

and GUI (HTTP and HTTPS)

• RADIUS, TACACS and TACACS+ login authentication

• Clear text router configuration files

• Downloadable router configuration files via TFTP

o A standard router configuration policy can be enforced via DOCSIS config file

vendor specific TLV

• DHCP server for static IP block

• Ethernet MAC address filtering

• Diagnostic tools

5.2 Out of Box Setup

• Physically mount the Outdoor Cable Modem as indicated in figures 2-1 or 2-2

• Provision the cable modem as any other standalone DOCSIS modem on the system

o The RF MAC for provisioning can be found on the side of the box or on the

sticker on the bottom of the unit.

• When in Router Mode the Outdoor Cable Modem CPE interface is enabled

• Provision the CPE interface as any other customer premise device connected to a

standard cable modem. In most cases, nothing needs to be done in the provisioning system to enable the CPE Ethernet interface.

5.3 Defaults

The SMC8511 Outdoor Cable Modem (OCM) defaults to the following:

• Bridge Mode

• CPE / remote management interface – disabled

• Web server (GUI)

o RF interface – enabled on port 80 (HTTP) and 81 (HTTPS) o CPE / remote management interface enabled on port 8080 (HTTP) and 8181

(HTTPS)

• Telnet

o RF interface enabled on port 23 o CPE / remote management interface enabled on port 2323

• LAN IP

o In Bridge Mode – 192.168.100.1 o In Router Mode – 20.20.20.1

• DHCP server – Enabled

- 11 -

5.4 Principal Operating Modes

5.4.1 Bridge Mode

When in Bridge Mode:

• The Outdoor Cable Modem (OCM) only requests an RF interface IP address.

• Logon to 192.168.100.1 (Ethernet interface) or RF interface IP to put OCM into Router Mode.

• CPE (Ethernet) interface, Static IP and RIP are disabled.

5.4.2 Router Mode When in Router Mode:

• Default configuration – OCM requests both an RF interface IP (usually non-routable) and a

CPE / Remote Management interface IP (globally routable).

• By default, the CPE (Ethernet) interface is the RIP source IP.

• The Remote Management page defines ports on which the OCM listens for incoming

management requests to the CPE (Ethernet) interface.

• If ‘Use RF IP as the RIP source IP’ is selected, then the OCM will use RF IP as the RIP

source IP and will not pull a CPE (Ethernet) IP.

o LAN IP becomes CPE / Remote Management IP.

• If a static CPE (Ethernet) IP is configured, DNS values must be assigned. In this

configuration there are three IP addresses assigned to the OCM:

o RF o CPE / Remote Management o LAN
