Smart Routers ATM and TDM Configuration Guide 10 76.8600-50110F © 2015 Coriant TDM Overview 8.4 TDM Pseudowire OAM (L, M, R) The L, M and R bits (located in pseudowire Control Word) used for TDM PWE3 OAM are specified in [RFC4553] for SAToP PWE3 and in [RFC5086] for CESoPSN PWE3 The L-bit, if set indicates that TDM data carried in the payload is invalid The replacement data used when L bit is received is user-configurable, but the optional payload suppression feature in the transmitting side is not supported The M-bits forming the 2-bit modifier field are used in CESoPSN only for carrying RDI of the attachment circuit across the PSN Since only basic NxDS0 Services without CAS are supported, there is no need for discrimination of signalling packets based on the M-bits The R-bit, if set by the PSN-bound Interworking Function (IWF) indicates that its local CE-bound IWF is in the packet loss state 8.5 References [RFC4197] RFC4197 (2005–10), Requirements for Edge-to-Edge Emulation of

Configuration Examples TDM Cross-Connection and Tunnelling Configuration Examples It is advisable to simultaneously refer to: • 8600 Smart Routers Interface Configuration Guide for more information on the interface configuration such as SDH and PDH layers; • 8605 Smart Router Interface Configuration Guide for more details on the interface configuration of the PDH layer; • 8607 Smart Router Interface Configuration Guide for more details on the interface configuration of the PDH layer; • 8609 Smart Router and 8611 Smart Router Interface Configuration Guide for more details on the interface configuration of the PDH layer Moreover, to avoid unnecessary configuration, see the default values in 8600 Smart Routers CLI Commands Manual 9.1 Configuring Local T1 Cross-Connections This example shows how an internal T1 cross-connection is configured between a native T1 PDH port and a channelized OC-3 SONET port within a single 8600 network element 76.8600-50110F © 2015 Coriant 8600 Smart Routers ATM and TDM Configuration Guide 151 TDM Cross-Connection and Tunnelling Configuration Examples Fig 50 Local Internal Cross-Connection Step First define to the system the cross-connection entity called PWE3 circuit This entity represents the cross-connection inside the 8600 system with a unique name (t1_circuit_1) and a unique system internal instance ID (23) number If the name or ID is not unique in the command, the system denies the creation of the PWE3 circuit router(config)# pwe3 circuit t1_circuit_1 23 mpls manual Step Configure both T1 connection points For structure agnostic circuits, the ports are set to connected mode, i.e the T1 framing structure is not terminated Since the PWE3 circuit is used for internal cross-connection purposes, delays can in practise be optimized by configuring a considerably smaller payload size and jitter buffer settings than the default values However, since the minimum supported T1 SAToP payload size of 48 bytes corresponds to 250 microseconds of TDM data, the default value for the jitter buffer target is 500 microseconds, and there is no need to explicitly adjust the target through the CLI router(config)# interface pdh

created in the first step router(config)# mpls static-ftn bridge t1_circuit_1 pdh 4/1/0 so 10/0/0:1:1:1 router(config)# mpls static-ftn bridge t1_circuit_1 so 10/0/0:1:1:1 pdh 4/1/0 9.2 Configuring E1 SAToP Tunnelling over Wide Area IP/MPLS Network The following example shows how an E1 circuit is configured to be connected over an IP/MPLS wide area network using PWE3 SAToP tunnelling, with a focus on the CLI commands needed for establishing pseudowire connectivity over the packet-switched network The example uses the default setting for the E1 SAToP payload size (i.e 256 bytes), but the jitter buffer target depth is adjusted to 5000 microseconds in order to better match the latency characteristics of the IP/MPLS WAN core Note that the general configuration of the MPLS interfaces and the related routing protocols is also not completely covered in this example For additional details refer to 8600 Smart Routers MPLS Applications Configuration Guide and 8600 Smart Routers Routing Protocols Configuration Guide Fig 51 E1 SAToP PWE3 over IP/MPLS PSN Node-103 configuration: Step Initialize a PWE3 circuit in the Node-103 with a circuit name and a pseudowire ID Use LDP to setup the required pseudowire label bindings, and use the expedited forwarding traffic class for carrying the TDM circuit through the MPLS network to the target node 10.123.100.223 Note that the PWE3 circuit name and the ID are unique within the scope of a single NE, and that the ID also has to be identical at both ends of the PWE3 router-103(config)# pwe3 circuit ldp-satop-1 103 mpls ldp 10.123.100.223

structure agnostic tunnelling, the TDM interface is set to connected mode, i.e the TDM framing structure is not terminated Note that the jitter buffer target setting always has to be a multiple of the packetization delay, which for the default E1 payload size of 256 bytes is 1000 microseconds After no shutdown, LDP starts the pseudowire setup signalling to the target node router-103(config)#

BFD VCCV BFD configuration details are covered in 8600 Smart Routers Test and Measurement Configuration Guide 9.3 Configuring NxDS0 CESoPSN Mobile Backhaul over Metro Ethernet with Adaptive Timing The following example shows how an NxDS0 circuit is configured to be connected over an IP/MPLS-enabled Metro Ethernet network, when using PWE3 CESoPSN tunnelling for latency-sensitive mobile backhaul applications Again, the focus is on the CLI commands needed for establishing pseudowire connectivity over the packet-switched network, assuming that basic connectivity between the 8600 network elements has already been established, so it should be noted that the general configuration of the MPLS interfaces and the related routing protocols is not completely covered For additional details refer to 8600 Smart Routers MPLS Applications Configuration Guide and 8600 Smart Routers Routing Protocols Configuration Guide In order to meet the rather strict end-to-end delay budget requirements associated with some mobile backhaul scenarios, the example uses rather tightly engineered packetization delay and jitter buffering settings, i.e the delay introduced by the jitter buffer is kept within 3000 microsecond bounds under all network conditions Furthermore, adaptive timing is used in the BTS facing 8605 Smart Router, both for the physical CESoPSN attachment circuit, and also for a pre-configured ATM attachment circuit Thus, the example focuses on the NxDS0 CESoPSN configuration Fig 52 NxDS0 CESoPSN PWE3 over Metro Ethernet with Adaptive Timing Node-103 configuration: Step Initialize a PWE3 circuit in the element with a circuit name and a pseudowire ID Use LDP to setup the required pseudowire label bindings, and use the expedited forwarding traffic class for carrying the TDM circuit through the Metro Ethernet network to the target node 10.123.100.223 76.8600-50110F © 2015 Coriant 8600 Smart Routers ATM and TDM Configuration Guide 155 TDM Cross-Connection and

transport The default NxDS0 CESoPSN payload size for N=10 is 8*10 = 80 bytes Again, the jitter buffer target setting has to be a multiple of the packetization delay, which in the N=10 case is 1000 microseconds by default, so a target of 2000 microseconds is chosen The default maximum delay setting of twice the target delay is also overridden, in order to keep the jitter buffer delay within 3000 microsecond bounds under any network conditions After no shutdown, LDP starts the pseudowire setup signalling to the target node router-103(config)# interface pdh 1/0:0 router-103(cfg-if[pdh1/0:0])#

router-103(cfg-if[pdh1/0:0])# no shutdown router-103(cfg-if[pdh1/0:0])# exit Step The CESoPSN pseudowire carrying timeslot group is chosen as the adaptive timing source for the interface If SAToP was used, there would be only one pseudowire terminating on the interface, and thus there would be no need to indicate any selection of the adaptive timing source router-103(config)# interface pdh 1/0 router-103(cfg-if[pdh1/0])# pdh adaptive-timing local pdh 1/0:0 router-103(cfg-if[pdh1/0])# exit Step The same adaptive timing source can also be used for synchronizing other physical interfaces, but only within the same interface module In this example, interface pdh1/1 used for ATM pseudowire tunneling will also receive its timing from the created CESoPSN pseudowire For instructions on
