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

for details of the mounting assemblies.

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

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

•Power over Ethernet (PoE)1through the water resistant RJ45 Ethernet connector.

In addition, when the SMC8511 Outdoor Cable Modem is powered from the CATV system

through its F-connector interface, it can optionally

provide

24 VDC at 0.5 amps

from

the Ethernet

port to power the external Ethernet device.

Figure 3-1 Power from CATV System

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.

Above configuration (Fig 3-2) is particularly useful in a lab/shop environment where DOCSIS is

available but without power. A power injector2fed with 24 VDC with at least 1 amp capacity

powers the SMC8511 through 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.

3.3 Power Output to PoE

When the SMC8511 Outdoor Cable Modem is powered from the CATV system through its F-

connector interface, it can optionally

provide

24 VDC at 0.5 amps

from

the Ethernet port to

power the external Ethernet device. The wiring /pin connections are given in Figure 3-3, below.

3.4 PoE Wiring

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.

Figure 3-3 PoE Wiring

Note that this PoE implementation differs from both the IEEE 802.3-2005 and draft IEEE 802.3af

standards.

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.

Figure 4-1 SMC8511 Simplified Block Diagram

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

oA 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

oThe 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.
