Applications
Regional |
In Figure 1-3, the public network (Frame Relay/X.25) is performing the branch |
Concentrator |
concentration function with the PathBuilder S24x, 26x, and 27x switch routing the |
|
traffic to the appropriate end point. In Figure 1-4, the PathBuilder S24x, 26x, and |
|
27x switch acts as the regional concentrators, receiving traffic from dozens and even |
|
thousands of remote sites, and concentrating the traffic before forwarding it to the |
|
correct location. In this case, the PathBuilder S24x, 26x, and 27x switch is the |
|
regional site. |
In both examples, the PathBuilder S24x, 26x, and 27x switch could be either a single node or a group of nodes networked together as a cluster. The PathBuilder S24x, 26x, and 27x switch’s cluster feature is described below.

Figure 1-4. Regional Concentrator Example
Cluster Application An important new feature available with the PathBuilder S24x, 26x, and 27x switch is its use in a cluster. This allows as many as four PathBuilder S24x, 26x, and 27x switches to act a single unit for the purposes of connectivity. Though configured and managed as individual nodes, when the PathBuilder S24x, 26x, and 27x switches are clustered together, devices attached to access ports on one node can have calls routed out the network port of one of the other nodes.
The three high-speed ports on the PathBuilder S24x, 26x, and 27x switch motherboard provide networking channels between the nodes to pass traffic from network ports to access ports. The PathBuilder S24x, 26x, and 27x switch cluster allows for high port count and throughput primarily in support of the regional concentrator applications.
The example in Figure 1-5 is a full mesh cluster which means that any access link can reach any host connection. If a PathBuilder S24x, 26x, and 27x switch node within the cluster fails, only those links and host connections directly connected to that node go down. Placement of host equipment, and use of redundant host equipment can minimize the impact of any individual node failure. Furthermore, Link Back Up features in the remotes can limit the degree of remote isolation if part of the PathBuilder S24x, 26x, and 27x switch cluster fails.

Introduction |
|
This section provides detailed information about the parts of the PathBuilder S24x, |
|
|
26x, and 27x switch enclosure. |
Front Panel |
|
The PathBuilder S24x, 26x, and 27x switch front panel (see Figure 1-6) has: |
|
|
• Three status LEDs |
|
• A 2-character numeric LED display |
|
• A RESET switch |
Status LEDs |
|
The three status LEDs are: |
|
|
• Power (green) — When on, indicates that power is on and all DC voltages are |
|
within specifications. |
|
• Status (green) — When on, indicates that the PathBuilder S24x, 26x, and 27x |
|
switch node is executing either a power-up diagnostic or a software download. |
|
This LED is normally off. |
|
• Service (yellow) — When on, indicates a hardware failure. This LED is |
|
normally off. |
Numeric LED |
|
The 2-character numeric LED display provides system diagnostic codes. When the |
|
Display |
Service LED is on, a 2-digit code on the numeric LED display corresponds to a |
|
certain event. |
Reset Switch |
|
The RESET switch resets the node. Pressing the RESET switch is the equivalent of a |
|
|
power-up operation which clears all existing calls and brings down all links. |
Power Supply |
|
The power supply is mounted at the top rear of the chassis. The AC switchable power |
|
|
supply can operate at a nominal 110 or a nominal 230 Volts. For information about |
|
maintaining and replacing the power supply, refer to Chapter 4, Maintenance. |
Note
For this unit, the -48VDC Power Option is also available.

FLASH SIMM |
The FLASH Single In-line Memory Module (SIMM) holds a compressed image of |
|
the operating software. This module is electrically erasable and reprogrammable. |
|
An optional FLASH SIMM can be installed for backup. These modules are installed |
|
in one of the SIMM slots (1 or 2). Figure 1-8 shows the SIMM. |

|
|
|
|
|
|
The chips on your SIMM may vary from the one shown inFigure 1-8. |
CMEM SIMM |
|
|
|
||
The Configuration Memory Module (CMEM) SIMM has 512 Kbytes of memory and |
|||||
|
|
|
provides the real time clock function. The CMEM is backed up by a lithium battery |
||
|
|
|
in case of a power disruption. |
||
|
|
|
Each PathBuilder S24x, 26x, and 27x switch has a Software Serial Number (SSN) |
||
|
|
|
burned into a PROM located on the CMEM card. This SSN is used to verify the |
||
|
|
|
software options that are enabled for that node. It is on the CMEM SIMM card for |
||
|
|
|
easy removal and replacement in case of a motherboard failure. |
||
|
|
|
The CMEM is installed in the SIMM slot (see Figure 1-7 for slot location). |

Expansion Port The PathBuilder S24x, 26x, and 27x switch motherboard has eight full-size
I/O Slots expansion card slots (see Figure 1-6). Expansion I/O cards have I/O connectors that extend through the rear panel.
Port numbers for the ports on the I/O cards have a fixed relationship to the chassis expansion slot number. Six port numbers are reserved for each slot. If a slot contains an I/O card that does not support the full port count reserved for that slot, or the slot is empty, the extra port numbers remain unused.

Description |
|
Each E1 dual port digital PBX interface card uses an Industry Standard Architecture |
|
|
(ISA) bus interface and a Multi-Vendor Integration Protocol (MVIP) bus interface. |
|
The MVIP bus interface provides a multiplexed digital access within the PathBuilder |
|
S24x, 26x, and 27x switch chassis. |
|
The E1 dual port digital PBX interface card has two E1 ports (CAS signaling only), |
|
handles E1 lines with or without CRC4, and supports 120Ω and 75Ω (with the |
|
addition of an optional cable). The interface type is 8-pin modular. |
Function |
|
E1 dual port digital PBX interface cards provide the digital interfaces for |
|
|
connections to a PBX. The dual port digital PBX interface cards bring PCM voice |
|
and channel signaling into the node. The PCM voice data and voice signaling is |
|
routed to a DSPM/SM card over the MVIP bus for compression and transmission to |
|
the motherboard. |
Slot Restriction |
|
The E1 dual port digital PBX interface card can only occupy slot 8 in the PathBuilder |
|
|
S24x, 26x, and 27x switch chassis. |
