1.4.4 SNMP, TELNET and TL1 over 10BaseT
When the SCU is installed into Total Access 3000/3010, the 10BaseT connection is
enabled. An RJ45 port (J32 labeled E-NET) provided on the backplane connects the
system to an IP/Lan network. The SCU has a Standard TCP/IP stack and can operate
on a standard IP network.
The Total Access 3000/3010 shelves should not be daisy-chained when using
SNMP. With SNMP, each shelf should be equipped with a SCU and
connected to an Ethernet hub.
The Network Administrator must assign an IP address, subnet mask, and a default
gateway to the SCU.
The TELNET feature of Total Access 3000/3010 supports standard TELNET client
software. In a TELNET session, the user gets the same VT-100 menu as would be seen
on the craft interface.
The SCU provides support for up to four SNMP hosts. Access security is provided via
standard community name strings. The SCU also provides a TL1 machine interface
that can be accessed using a configurable TCP/IP port number. See Figure 5.

Network Timing

Because of the versatility of the shelf, several clocking schemes are supported. Both 64
kbps composite clock and DS1 redundant clocks are accommodated. See Figure 6.
1.5.1

64 KHz Composite Clock

Composite clock termination is provided by connector P4/P10, labeled as "EXTCLK
A-IN." The daughter module (P/N 1181940L1) located next to P4/P10 provides for
termination options. See Figure 4 in SYS-101, Flag C1.
1.5.2

DS1 Clock

For SONET or DS3 applications, the shelf provides for primary and secondary DS1
timing sources. The primary clock should be connected to P18/P11, labeled "B-IN."
The secondary clock should be connected to P24/P13, labeled "EXTCLK C-IN." The
multiplexer modules contain all necessary circuitry for proper operation. See Figure 4
in SYS-101, Flags C2 and C3.
1.5.3

External Clock

Because some applications may require the shelf to provide source timing, two
additional wire-wrap connections are provided: P19/P12 and P20/P9, "A-OUT" and
"B-OUT," are connected to MUXes A and B respectively. See Figure 4 in SYS-101,
Flag D. See Figure 7 for clocking functions.
