Note
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.
The Cisco ONS 15454 SDH integrates Ethernet into a SDH time-division multiplexing (TDM) platform. This chapter describes the Cisco ONS 15454 SDH E-Series Ethernet cards, the G-Series Ethernet cards, and ML-Series Ethernet cards. It includes descriptions, hardware specifications, and block diagrams for each card. For G-Series and E-Series Ethernet application information, see Chapter 13, "Ethernet Operation." For installation and card turn-up procedures, refer to the Cisco ONS 15454 SDH Procedure Guide. For ML-Series configuration information, see the Cisco ONS 15454 SONET/SDH ML-Series Multilayer Ethernet Card Software Feature and Configuration Guide.

Note
5.2 E100T-G Card
The ONS 15454 uses E100T-G cards for Ethernet (10 Mbps) and Fast Ethernet (100 Mbps). Each card provides 12 switched, IEEE 802.3-compliant, 10/100BaseT Ethernet ports that can independently detect the speed of an attached device (autosense) and automatically connect at the appropriate speed. The ports auto-configure to operate at either half or full duplex and determine whether to enable or disable flow control. You can also configure Ethernet ports manually. Figure 5-1 shows the faceplate and a block diagram of the card.
Figure 5-1 E100T-G Faceplate and Block Diagram
The E100T-G Ethernet card provides high-throughput, low-latency packet switching of Ethernet traffic across a SDH network while providing a greater degree of reliability through SDH "self-healing" protection services. This Ethernet capability enables network operators to provide multiple 10/100 Mbps access drops for high-capacity customer LAN interconnects, Internet traffic, and cable modem traffic aggregation. It enables the efficient transport and co-existence of traditional TDM traffic with packet-switched data traffic.
Each E100T-G card supports standards-based, wire-speed, Layer 2 Ethernet switching between its Ethernet interfaces. The IEEE 802.1Q tag logically isolates traffic (typically subscribers). IEEE 802.1Q also supports multiple classes of service.
5.2.1 Slot Compatibility
You can install the E100T-G card in any multi-speed or high-speed slot (Slots 1 to 6 and 12 to 17). Multiple E-Series Ethernet cards installed in an ONS 15454 can act independently or as a single Ethernet switch. You can create logical SDH ports by provisioning a number of SDH channels to the packet switch entity within the ONS 15454 SDH. Logical ports can be created with a bandwidth granularity of VC-4. In single-card, multi-card or port-mapped mode, the E-Series supports one VC-4-1c, two VC-4-2c, or four VC-4-4c signal levels.
5.2.2 E100T-G Card-Level Indicators
The E100T-G card faceplate has two card-level LED indicators (Table 5-4).
5.2.3 E100T-G Port-Level Indicators
The E100T-G card also has 12 pairs of LEDs (one pair for each port) to indicate port conditions (Table 5-5). You can find the status of the E100T-G card port using the LCD screen on the ONS 15454 fan-tray assembly. Use the LCD to view the status of any port or card slot; the screen displays the number and severity of alarms for a given port or slot.
5.2.4 E100T-G Card Specifications

5.3 E1000-2-G Card
The ONS 15454 uses E1000-2-G cards for Gigabit Ethernet (1000 Mbps). The E1000-2-G card provides two IEEE-compliant, 1000-Mbps ports for high-capacity customer LAN interconnections. Each port supports full-duplex operation.
The E1000-2-G card uses GBIC modular receptacles for the optical interfaces. For details, see the "Ethernet Gigabit Interface Converters (GBICs)" section.
Figure 5-2 shows the card faceplate and a block diagram of the card.
Figure 5-2 E1000-2-G Faceplate and Block Diagram
The E1000-2-G Gigabit Ethernet card provides high-throughput, low-latency packet switching of Ethernet traffic across a SDH network while providing a greater degree of reliability through SDH "self-healing" protection services. This enables network operators to provide multiple 1000-Mbps access drops for high-capacity customer LAN interconnects. It enables efficient transport and co-existence of traditional TDM traffic with packet-switched data traffic.
Each E1000-2-G card supports standards-based, Layer 2 Ethernet switching between its Ethernet interfaces and SDH interfaces on the ONS 15454. The IEEE 802.1Q VLAN tag logically isolates traffic (typically subscribers).
Multiple E-Series Ethernet cards installed in an ONS 15454 can act together as a single switching entity or as independent single switches supporting a variety of SDH port configurations.
You can create logical SDH ports by provisioning a number of SDH channels to the packet switch entity within the ONS 15454 SDH. Logical ports can be created with a bandwidth granularity of VC-4. In single-card, multi-card or port-mapped mode, the E-Series supports one VC-4-1c, two VC-4-2c, or four VC-4-4c signal levels.
5.3.1 Compatibility
The E1000-2-G is compatible with any traffic card slots (Slots 1 to 6 and 12 to 17).
5.3.2 E1000-2-G Card-Level Indicators
The E1000-2-G card faceplate has two card-level LED indicators (Table 5-6).
5.3.3 E1000-2-G Port-Level Indicators
The E1000-2-G card also has one bicolor LED per port (Table 5-7). When the green LINK LED is on, carrier is detected, meaning an active network cable is installed. When the green LINK LED is off, an active network cable is not plugged into the port, or the card is carrying unidirectional traffic. The amber port ACT LED flashes at a rate proportional to the level of traffic being received and transmitted over the port.
5.3.4 E1000-2-G Card Specifications
The E1000-2-G card has the following specifications:
•
–
C-Temp (15454-E1000-2-G): 0 to +55 degrees Celsius

5.4 G1000-4 Card
The ONS 15454 uses G1000-4 cards for Gigabit Ethernet (1000 Mbps). The G1000-4 card provides four ports of IEEE-compliant, 1000-Mbps interfaces. Each port supports full-duplex operation for a maximum bandwidth of OC-48 on each card.
The G1000-4 card uses GBIC modular receptacles for the optical interfaces. For details, see the "Ethernet Gigabit Interface Converters (GBICs)" section.
Figure 5-3 shows the card faceplate and the block diagram of the card.
Figure 5-3 G1000-4 Faceplate and Block Diagram
The G1000-4 Gigabit Ethernet card provides high-throughput, low latency transport of Ethernet encapsulated traffic (IP and other Layer 3 protocols) across a SDH network. Carrier-class Ethernet transport is achieved by hitless (< 50 ms) performance in the event of any failures or protection switches (such as 1+1 APS, path protection configuration, or BLSR). Full provisioning support is possible via CTC, TL1, or CTM.
Valid circuit sizes for a G-Series circuit are VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, and VC4-16c.
5.4.1 VC4-8c Restriction
Due to hardware constraints, the card imposes an additional restriction on the combinations of circuits that can be dropped onto a G-Series card. These restrictions are transparently enforced by the ONS 15454, and you do not need to keep track of restricted circuit combinations.
When a single VC4-8c terminates on a card, the remaining circuits on that card can be another single VC4-8c or any combination of circuits of VC4-4c size or less that add up to no more than VC4-4c.
If VC4-8c circuits are not being dropped on the card, the full VC4-16c bandwidth can be used with no restrictions (for example using either a single VC4-16c or four VC4-4c circuits).
Note
5.4.2 G1000-4 Card-Level Indicators
The G1000-4 card faceplate has two card-level LED indicators (Table 5-8).
5.4.3 G1000-4 Port-Level Indicators
The G1000-4 card also has one bicolor LED per port. Table 5-9 describes the status that each color represents.
5.4.4 Compatibility
The G-Series card is compatible in any multi-speed or high-speed traffic slots (Slots 1 to 6 and 12 to 17), for a total shelf capacity of 48 Gigabit Ethernet ports. The practical G1000-4 port per shelf limit is 40, because at least two slots are typically filled by OC-N trunk cards such as the OC-192.
5.4.5 G1000-4 Card Specifications
The G1000-4 card has the following specifications:
•
–
C-Temp (15454-G1000-4): 0 to +55 degrees Celsius–

5.5 G1K-4 Card
The G1K-4 card is the functional equivalent of the G1000-4 card and provides four ports of IEEE-compliant, 1000-Mbps interfaces. Each interface supports full-duplex operation for a maximum bandwidth of 1 Gbps or 2 Gbps bidirectional per port, and 2.5 Gbps or 5 Gbps bidirectional per card. Each port autonegotiates for full duplex and 802.3x flow control. The G1K-4 card uses GBIC modular receptacles for the optical interfaces. For details, see the "Ethernet Gigabit Interface Converters (GBICs)" section.
Figure 5-4 shows the card faceplate and the block diagram of the card.
Warning

Warning
The G1K-4 Gigabit Ethernet card provides high-throughput, low-latency transport of Ethernet encapsulated traffic (IP and other Layer 3 protocols) across a SDH network while providing a greater degree of reliability through SDH "self-healing" protection services. Carrier-class Ethernet transport is achieved by hitless (< 50 ms) performance in the event of any failures or protection switches (such as 1+1 APS, path protection configuration, BLSR, or optical equipment protection) and full provisioning and manageability, as in SDH service. Full provisioning support is possible via CTC or CTM. Each G1K-4 card performs independently of the other cards in the same shelf.
5.5.1 VC4-8c Restriction
Due to hardware constraints, the card imposes an additional restriction on the combinations of circuits that can be dropped onto a G-Series card. These restrictions are transparently enforced by the ONS 15454, and you do not need to keep track of restricted circuit combinations.
When a single VC4-8c terminates on a card, the remaining circuits on that card can be another single VC4-8c or any combination of circuits of VC4-4c size or less that add up to no more than VC4-4c.
If VC4-8c circuits are not being dropped on the card, the full VC4-16c bandwidth can be used with no restrictions (for example using either a single VC4-16c or four VC4-4c circuits).
Note
5.5.2 Compatibility
Software R4.0 and later identifies G1K-4 cards as G1K-4s upon physical installation. Software prior to R4.0 identifies both G1000-4 and G1K-4 cards as G1000-4s upon physical installation.
You can install the G1K-4 card into any multi-speed or high-speed traffic slots (Slots 1 to 6 and 12 to 17), for a total shelf capacity of 48 Gigabit Ethernet ports. (The practical limit is 40 ports because at least two slots are typically populated by optical cards such as the OC-192.)
5.5.3 G1K-4 Card-Level Indicators
The G1K-4 card faceplate has two card-level LED indicators, listed in Table 5-10.
5.5.4 G1K-4 Port-Level Indicators

5.6 ML100T-12 Card
The ML100T-12 card provides 12 ports of IEEE 802.3-compliant, 10/100 interfaces. Each interface supports full-duplex operation for a maximum bandwidth of 200 Mbps per port and 2.488 Gbps per card. Each port independently detects the speed of an attached device (autosenses) and automatically connects at the appropriate speed. The ports autoconfigure to operate at either half or full duplex and can determine whether to enable or disable flow control. For ML-Series configuration information, see the Cisco ONS 15454 SONET/SDH ML-Series Multilayer Ethernet Card Software Feature and Configuration Guide.
