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, 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 16, "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.

Table 5-3 shows C-Temp and I-Temp compliant cards and their product names.
Note
5.1.4 Ethernet Clocking Versus SONET/SDH Clocking
Ethernet clocking is asynchronous. IEEE 802.3 clock tolerance allows some links in a network to be as much as 200 ppm (parts or bits per million) slower than other links (0.02%). A traffic stream sourced at line rate on one link may traverse other links which are 0.02% slower. A fast source clock, or slow intermediate clocks, may limit the end-to-end thoughput to only 99.98% of the source link rate.
Traditionally, Ethernet is a shared media that is under utilized except for brief bursts which may combine from multiple devices to exceed line-rate at an aggegration point. Due to this utilization model, the asynchronous clocking of Ethernet has been acceptable. Some Service Providers accustomed to loss-less TDM transport may find the 99.98% throughput guarantee of Ethernet surprising.
Clocking enhancements of ML-Series and G-Series cards ensure Ethernet transmit rates that are at worst 50 ppm slower than the fastest compliant source clock, ensuring a worst-case clocking loss of 50 ppm - a 99.995% throughput guarantee. In many cases, the ML-Series or G-Series clock will be faster than the source traffic clock, and line-rate traffic transport will have zero loss. Actual results will depend on clock variation of the traffic source transmitter.
5.2 E100T-G Card
The ONS 15454 SDH 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 autoconfigure 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 E100T-G Slot Compatibility
You can install the E100T-G card in Slots 1 to 6 and 12 to 17. Multiple E-Series Ethernet cards installed in an ONS 15454 SDH 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.
5.2.2 E100T-G Card-Level Indicators
The E100T-G card faceplate has three 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 SDH 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
The E100T-G card has the following specifications:
•

5.3 E1000-2-G Card
The ONS 15454 SDH 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 "GBICs and SFPs" 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 SDH. The IEEE 802.1Q VLAN tag logically isolates traffic (typically subscribers).
Multiple E-Series Ethernet cards installed in an ONS 15454 SDH 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.
5.3.1 E1000-2-G 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 three 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 LINK LED is illuminated green, carrier is detected, meaning an active network cable is installed. When the LINK LED is not illuminated green, an active network cable is not plugged into the port, or the card is carrying unidirectional traffic. The port ACT LED flashes amber 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:

5.4 G1000-4 Card
The ONS 15454 SDH 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 STM-16 on each card.
The G1000-4 card uses GBIC modular receptacles for the optical interfaces. For details, see the "GBICs and SFPs" 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 automatic protection switching [APS], path protection, or bidirectional line switched ring [BLSR]). Full provisioning support is possible via Cisco Transport Controller (CTC) or Cisco Transport Manager (CTM). Each G1000-4 card performs independently of the other cards in the same shelf.
5.4.1 G1000-4 Card-Level Indicators
The G1000-4 card faceplate has two card-level LED indicators (Table 5-8).
5.4.2 G1000-4 Port-Level Indicators
The G1000-4 card has one bicolor LED per port. Table 5-9 describes the status that each color represents.
5.4.3 G1000-4 Compatibility
The G-Series card operates in 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.
5.4.4 G1000-4 Card Specifications
The G1000-4 card has the following specifications:

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 IEEE 802.3x flow control. The G1K-4 card uses GBIC modular receptacles for the optical interfaces. For details, see the "GBICs and SFPs" 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, 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 G1K-4 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 in 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.)

1 When using an LX SFP or LX GBIC with multimode fiber, you must install a mode-conditioning patch cord between the SFP/GBIC and the multimode fiber cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances less than 100 m (328 feet) or greater than 300 m (984 feet). The mode-conditioning patch cord prevents overdriving the receiver for short lengths of multimode fiber and reduces differential mode delay for long lengths of multimode fiber.
5.8.1 DWDM and CWDM Gigabit Interface Converters
DWDM and CWDM GBICs operate in the ONS 15454 SDH G-Series card when the card is configured in Gigabit Ethernet Transponding mode or Ethernet over SONET mode. DWDM and CWDM GBICs are both wavelength division multiplexing (WDM) technologies and operate over single-mode fibers with SC connectors. Cisco CWDM GBIC technology uses a 20-nm wavelength grid and Cisco ONS 15454 SDH DWDM GBIC technology uses a 1-nm wavelength grid. CTC displays the specific wavelengths of the installed CWDM or DWDM GBICs. DWDM wavelengths are spaced closer together and require more precise lasers than CWDM. The DWDM spectrum allows for optical signal amplification. For more information on G-Series card transponding mode, see the"16.2 G-Series Gigabit Ethernet Transponder Mode" section on page 16-5.
The DWDM and CWDM GBICs receive across the full 1300-nm and 1500-nm bands, which includes all CWDM, DWDM, LX, ZX wavelengths, but transmit on one specified wavelength. This capability can be exploited in some of the G-Series transponding modes by receiving wavelengths that do not match the specific transmission wavelength.
Note
Note
The ONS 15454 SDH supported CWDM GBICs reach up to 100 to 120 km over single mode fiber and support eight wavelengths:
•
•
•
•
•
•
•
•
The ONS 15454 SDH supported DWDM GBICs support 32 different wavelengths in the red and blue bands. Paired with optical amplifiers, such as the Cisco ONS 15216, the DWDM GBICs allow maximum unregenerated spans of approximately 300 km (Table 5-17).
5.8.1.1 Placement of CWDM or DWDM GBICs
CWDM or DWDM GBICs for the G-Series card come in set wavelengths and are not provisionable. The wavelengths are printed on each GBIC (for example, CWDM-GBIC-1490). The user must insert the specific GBIC transmitting the wavelength required to match the input of the CWDM/DWDM device for successful operation (Figure 5-7). Follow your site plan or network diagram for the required wavelengths.
Figure 5-7 CWDM GBIC with Wavelength Appropriate for Fiber-Connected Device
The Cisco ONS 15454 SDH Procedure Guide contains specific procedures for attaching optical fiber to GBICs and inserting GBICs into the G-Series card.
5.8.1.2 Example of CWDM or DWDM GBIC Application
A G-Series card equipped with CWDM or DWDM GBICs supports the delivery of unprotected Gigabit Ethernet service over Metro DWDM and video on demand (VoD) transport networks (Figure 5-8). It can be used in short-haul and long-haul applications.
