ADPCM Card Introduction

Chapter 1 ADPCM Card

1.1 Introduction

This chapter provides installation, configuration, and troubleshooting information for the Adaptive Differential Pulse-Code Modulation (ADPCM) Card. This card is labeled as the ADPCM 64 card on its faceplate ejector.

1.2 ADPCM Card Descriptions

1.2.1 ADPCM 64 Card Description (887160)

The ADPCM 64 Card has 32 pairs of voice compression engines that accept inputs directly from voice, SRU, and/or BRI data cards in the same system unit, or voice traffic from WA N links through the system. This card requires a matching card at the other end to decompress the voice channels to normal 64 kbps operation.

With previous versions of the IMACS, signaling conversion was only supported for voice ports when routed over the WAN and not when routed through an ADPCM card. W ith version

5.3.1 and higher of the IMACS host CPU firmware, signa ling conversion i s also supported fo r voice channels routed through the ADPCM. The conversion table is the same as for passing the channel through a WAN, and available from the interface car d’s main scre en by sele cting “taBs”. Signaling conversion is enabled / disabled using the same SIG CONV parameter as used for conversion over a WAN. This field is found on Figure 1-1, the E & M Voice Card’s main screen.

Each pair of compression engines uses one 64 kbps DS0 time slot for two compressed voice channels. Each engine can compress 64 kbps voice traffic into 24 kbps, 32 kbps, or 40 kbps, depending on the voice signal quality required.

The rate of a DS0 time slot i s 64 kbps, so the sum of the compression rates for engines 1 and 2 must equal 64 kbps. For example, if you assign a 32 kbps circuit to engine 1, engine 2 can only accept another 32 kb ps cir cuit. Al so, a 40 kb ps c ircuit c an only b e pa ired with a 24 kbp s circuit, and vice versa.

The ADPCM compression engines always work in pairs. Engines 1 and 2, 3 and 4, 5 and 6, and 7 and 8 are paired. Each member of the pair mus t have th e same ADPCM WAN port and ADPCM time slot. Also, both members of the compression engine pair must be active

before either port will operate.

ADPCM Card Descriptions ADPCM Card

The ADPCM 64 Card can transport low-s peed asy nchr onous da ta transmi ssion (19.2 kbps or less) from an SRU user card po rt that wil l occupy a 24 kbps engine. Each dat a circuit must be paired with a 40 kbps voice channel . The card can a lso compress B- channel voice traff ic from a BRI card without restricting compression rates.

The Integrated Access System can have up to three ADPCM 64 Cards (two normal cards and an identical redundant card).

The ADPCM 64 Card supports Transition Signaling as defined in ANSI T1.302-1989, with the exception of the Alarm bits. ANSI T1.302 specifies signaling at the 32 bps compression rate. The card uses t his scheme for 24 bps and 40 bps, even though those rat es are not incl uded in the standard . T able 1-1 summarizes the signals suppor ted by each t ranscoder data rate. Your DS0 time slot configuration must adhere to these specifications.

ST ATE

The State setting determines whether the port is active or inactive. When assigning ADPCM engine pairs for WAN traffic, set the State setting to stdby (standby) for por ts tha t are no t yet used or not yet configured. Set it to actv (active) for ports that are ready fo r use.

Setting the State to rdnt (redundant) for any port o n an unu sed card wi ll cause that ca rd to act as the redundant back-up for all of the other ADPCM cards in that unit. Once a card is designated as a redundant ADPCM card the only way it can be used for regular ADPCM traffic is to change the state of the selected port back to either actv or stdby.

When assigning ADPCM engine pairs from use r cards , changing the port from stdby to actv and saving the selection information on the user card screen will cause the system to automatically assign an ADPCM engine.

When the engine is assigned from a user card, no changes can be made from the ADPCM card screen to any of the fields.

USER

The User setting identifies the user card and port connected to this engine. This is the place where the ADPCM card will expect incoming (non-compressed) voice, subrate data, and B-channel traf fic. If assi gned from a voice, SRU, or BRI card port , this selec tion will show the user card slot and port n umber (e.g ., u5-2 for th e ca rd in sl ot U5, port 2). If you are as signi ng a WAN time slot, this setting will s how n/a.

WAN/SERV

The WAN/SERV setting identifies the incoming WAN link connected to this engine. This is the place where the ADPCM card will expect incoming (non-compressed) voice. If you are assigning voice traffic to a WAN time slot, this setting will show w1-1 to w4-2. If you are assigning to a voice card or SRU card port, this setting will show n/a.

The Time slot parameter selects the specific time slot of the above WAN link on which the ADPCM card can expect incoming voice traffic. If WAN 1-1 is equipped with a T1 CSU module or a DSX/CEPT module configured for T1 DSX interface, the options are 1 to 24. If a DSX/CEPT module is installed on that WAN port and that module is configured for CEPT E1 interface, the options are 1 to 15 and 17 to 31. If you are assigning time slots to voice or SRU card ports, this setting will be n/a.

ADPCM W/S

The ADPCM W/S setting identifies the out going WAN link to which the engine is connected. If you are assigning to a voice, SRU, or BRI card port, or to voice traffic from a WAN time slot, this setting will show w1-1 through w4-2. This is the WAN link to which the ADPCM card will send its outgoing (compressed) traffic.

ADPCM TS

The ADPCM Ti me slot para meter sel ects the specific tim e slot on the WAN link chosen in the previous setting that t he ADPCM card will send outgoing compr essed traf fic. The options are determined by the equipment on the WAN link selected in the previous setting. If WAN 1-1 is equipped with an 8 12 CSU or 811 DSX/CEPT Module conf igure d for DSX, t he opt ions are 1 to 24. If a DSX/CEP T module is installed a nd configure d for CEPT E1, the opt ions are 1 to 15 and 17 to 31.

ADPCM Card User Screens and Settings ADPCM Card

TYPE

The Type parameter identi f ies the voice and signaling requir ements for the incoming circui t. The options are v (voice), voice and v&s (si gnali ng) and trnsp (transparent). Use v when the input to the ADPCM channel is a 64 kbps channel and inband signaling is not required. Use v&s when the input to th e ADPCM cha nnel i s a 64 kbps voi ce cha nnel a nd the ADPCM card must also provide inband signaling.

The trnsp setting allows you to map the outputs of SRU ports to the ADPCM channel. The subrate data will be cl ocked into the ADPCM channe l at an inpu t rate of 24 kbp s, then pa ssed transparently (n on-compressed) through t he ADPCM card to the a ppr opr iat e WAN time slot. This could be useful if you have an odd number of voice channels and want to utilize the empty engine pair of the last ADPCM channel.

The B-channel traffic from the BRI card also uses the trnsp setting, but it does not place any restrictions on the compression rates.

If the engine is assigned to a voice card, this selection will sh ow v&s. If assigned to an SRU card, it will show trnsp. You cannot change it from this screen.

RATE

The Rate parameter identif ies the compression requirem ents for the incoming circuit. T he options are 24K, 32K, and 40K. The sum of the pair of engines must always equal 64 kbps.

If this engine is assigned to a user card port, the selection will show the value that was chosen on that port. It cannot be changed from this screen.

SIG MODE

The Signaling Mode parameter identifies the type of signaling required for the incoming circuit from the network. If v&s was chosen in the Type setting, the options are e&m, fxs, plar, and fxo. If v or trnsp was chosen in the Type setting, the only option is n/a.

If this engi ne is assigned t o a user card, this selection will show user. It cannot be changed from this screen.

CODING

The Coding parameter identifies the PCM companding format required for the incoming circuit from the network. The choices are u-law or a-inv.

If this engine is assigned to a voice or BRI card, this selection will show the value you selected for that port. If this engine is assigned to an SRU card, this selection will show u-law. It cannot be changed from this screen.

FRS Card Introduction

Chapter 2 FRS Card

2.1 Introduction

This chapter provides installation, configuration, and troubleshooting information for the Frame Relay Server (FRS) (881160) card with the 622xx Firmware.

Note that this card is labeled as an ACS card on its faceplate ejector. It is identified as an FRS card only in the u ser interf ace screens shown in this chapter. Through out the remai nder of this chapter, it will be r eferred to as the ACS-FRS card.

2.2 ACS-FRS Card Descriptions

2.2.1 ACS-FRS Card Description (881160)

The ACS-FRS card concentrates mult iple N x 56 K or N x 64K frame relay data stre ams onto one or more Nx56/64K links of the Integrated Access System. In addition to frame relay concentration, the card encapsulates data for Nx56/64K HDLC or SDLC data streams. The frame relay server software runs on the ca rd, which p rovides u p to 68 l ogical po rts. Up to 128 permanent virtual circuits (PVCs) can be configured on a single card. The aggregate speeds of all ports associated with each FRS cannot exceed 8 Mbps.

The maximum frame size sup ported by the ACS- FRS card is 4, 096 bytes per frame . Each card can switch 4,000 frames p er second, as suming a fram e size of 64 b ytes per fr ame. Up to thre e ACS-FRS cards can be used in a system.

2.2.1.1 Card Jumpers/Switch Settings

The ACS-FRS card does not have any jumpers or switches on its motherboard.

2.2.1.2 Installing the Card

Insert the ACS-FRS card into one of the server card chassis slots (P1 to P3) . The system can accommodate up to three server cards.

2.2.2 ACS-FRS Firmware Features (62220)

The ACS-FRS firmware release 62220 has the same functionality as the firmware release 62218 except for the addition of circuit priorities. The addition of these priorities will assure that traffic on higher priority circuits will be unaffected by traffic from lower priority circuits. Four queues will be impl emen ted so no traf fi c of lower priority wil l be al l owed to pass when there is traffic pending in a higher priority queue.

The overall objective is to pas s lower prior ity IP infor mati on alon g with vo ice tr af fic without affecting voice quality. The ACS-FRS card will upon congestion favor the higher priority queues. Lower priority queues will be buffered and transmitted if bandwidth becomes available before transmit buffers overflow.

The ACS-FRS card will direct frames according to their DLCI (Data Link Connection Identifier). IP Datagrams can be terminated on a LAN vi a the IPR (IP Router) card.

The maximum bandwidth possible between the IPR and ACS-FRS cards is 62 time slots provided on the internal buses “A” and “B.”

The “C1” and “C2” ports of the FRS card can not together be assigned mo re than 32 time sl ots due to hardware limi ta ti ons . The same is true for t he FRS ports “C3” and “C4”. A total of 6 4 time slots can be assigned all the “C” ports. A similar limitation exists for the ports 1-64 terminating the voice circuits. Each group of 32 ports, 1-32, and 32-64 share a common internal pipe limited to 32 ti me slots each. The maximum number of time slots allows per port is one when all ports per group is acti ve. If half th e number of ports of a group i s active, t wice the number of time slots can be assigned per port.

The maximum internal bandwidth between FRS cards and HSU cards of an Integrated Access System is limited by the pools size of 126, but also limited by usage from this pool by the IPR/FRS connections and possible voice card usage.

The Full Status Frequency (N391) allows you to select the number of “keep alive” messages (see T391 above) that s hould elapse before t he full status i nquiry message is se nt. The number of messages are 1 to 255. The default is 6.

ASYNC

This setting specifies whether a synchronous state's update messages are to be sent when changes on the link occur. If set to no, link updates are sent at regular intervals, in response to Full Status Requests.

CONG THRS

The Congestion Thresh old allows you to select the amoun t (in percenta ge) that the i nternal Tx queues on the port must be filled before declaring this port is congested (this information is communicated by FECN and BECN flags). The options are 1 to 100.The defaul t is 95.

Since DE (Discard-Eligibility) frames are not queued to the same extent as non-DE frames, DE-frames may be dropped when mixed with non-DE frames on the same port before congestion control is initiated.

T o assure congestion cont ro l is initiated even for DE-fr ames u nder the cond it ions mentioned above, the TX threshold value must be reduced sufficiently to match the percentage DE-frames being buffered.

2.3.2 Frame Relay Endpoints Screen

You can have up to four frame relay endpoints (two for the actual endpoints of the PVC and two that can act as backup should the primary link fail). All frame relay endpoints are inventoried on the Frame Relay Endpoints Screen, and all endpoints must be defined from this screen before the user can provision the circuit.

Figure 2-3 shows a typical Frame Relay Endpoints Screen, which can be viewed by pressing “e” (Endp) in the ACS-FRS Card Main Screen. Table 2-3 lists the actions you can perform from the bottom line of this screen.

NAME

The Name setting allows you to identify each of the endpoints with a discrete name. This setting is case-sensitive, so a endpoint called “P101” is not the same as one called “p101.” Circuits are built using these names.

PORT

The Port number identif ies the Frame Relay po rt used for this cir cuit. This informat ion is input by the user from the keyboard. Valid entries are C1 to C4 and 1 to 64.

DLCI

The Data Link Connection Identifier is a unique number assigned by the carrier to this endpoint. The number must be between 1 and 996 (ansi or ccitt), or 1 and 1007 (lmi). The oth er numbers within the 1023 range are reserved.

BC(Kb)

The Bits Committed setting defines the threshold for the transmit rate (outgoing frames) where the card will make every effort to deliver the traffic to the subscriber . The time used to average rate is determined by the card by dividing the Committed Information Rate (CIR) by Bc. The number input must be between 0 and 2048.

BE(Kb)

The Bits Excessive set ting define s the threshol d for the tra nsmit rate (ou tgoing fr ames) where the carrier will admit the frames into the network (in effect, this is the maximum transmission rate). Frames sent below this threshold but above the BC (KB) threshold are admitted into the carrier network with the DE (discard eligibility) bit set. If congestion occurs in the network, these frames are the first to be discarded. The options are 0 to 2048.

Action Function

Refresh Redraws the screen. New Adds new circuit endpoints for each of the Frame Relay ports dElete Deletes the highlighted endpo int s. The sy stem requires confirmation with a

yes/no question before deleting the circuit. pgUp Pages through the pages of Frame Relay endpoints from newest to oldest. pgDn Pages through the pages of Frame Relay endpoints from oldest to newest. Main Returns to the System Main Screen. If changes are made to settings and not

CIR (Kbps)

The Committed Information Rate (in kbps) is the actual information rate contracted with the carrier. The options are 0 to 2048. CIR/Bc is used to calculate average data rate.

When CIR is set to 0, all frames forwarded will ha ve the DE-bit set.

ALLOW RED

When Allow Red is set to yes transmit rate exceeding BC+Be will be forwarded if there is capacity available. When set to no forwarding will not be attempted.

2.3.3 FRS Circuits Screen

The FRS Circuits Screen allows you to identify PVC endpoints and alternate PVCs to serve as backups to the original endpoints if the main link fails. Endpoints must be inventoried on the PVC Endpoints Screen before they can be used to set up backup ci rcuits. Figure 2-4 shows a typical Circ uits Scre en, and Figur e 2-5 is a n endpoint circuit example. Table 2-4 lists the actions you can perform from the bottom of this screen.

Figure 2-4.Typical Circuits Screen

Currently the FRS is limited t o 128 circuit s connecting 256 endpoints. The Integrate d Access System is required to serve a maximum of 8 EBTS units, each having a total of 16 channels. Each EBTS can be address by three different IP addresses. Each IP address represents a specific type of servic e. Each of the ser vices: si gnaling, mess ing, and NMS will be addressed EBTS by a different IP address. The IP router card will encapsulate IP Datagrams for each service wi th a unique DLC I value. The IP frames are self-contained in th at channel information is embedded in the data of the datagram.

The total of 152 circuits will be required for both voice and IP circuits. Even though the maximum number of circuits for a single FRS card could be expanded to accommodate the needed number . When using two FRS cards, 64 ci rcuits per car d can be used as IP c ircuits after 64 circuits have been used as voice circuits.

2.4 ACS-FRS Card Error Messages

Refer to Appendix B in the System Reference Guide for further information on Error Messages reg arding this card.

2.5 ACS-FRS Card Troubleshooting

Problems with a FRS card could indicate a number of causes. Some possibilities are:

• T1 or E1 network failure

• Improper frame relay network configuration

• Improper FRS card configuration

• Improper user card configuration

• Faulty cabling between the DTE and user card

• Improper DTE configuration

T ypically, a problem is indicated by the inabil ity to send or receive fr ame relay traf fic th rough the FRS card. There are numerous ways of isolating and clearing the problem. When troubleshooting frame relay communications problems through an FRS card, follow this general sequence:

1. If all Frame Relay traf fic is af fected, verify that the US/EUR jumper is corre ctly placed to match the US/EUR jumper on the chassis. The FRS card performs a self-test on power-up. A “healthy” card will have a green LED lit on the front panel. Do not proceed with further steps until a green LED is present.

2. V eri fy that the T1 or E1 network is working properly by checking f or current CGA-Red and CGA-Yell ow alar ms (see Cha pter 3 -A for a larm vie wing ins truct ions) . If no CGA alarms are present that would affect the frame relay traffic, continue with step 3.

3. V er ify that the FRS port is connected to the prope r WAN card and time slot or user card port and that the correct type of LMI is selected. If a user card port is used, verify the configuration settings on the user card port and the cable connection to the DTE. The LMI must be UP for data to flow on the circ uit. Do not pr oceed with fur ther step s until the LMI is up.

4. Go to the Port Performance Monitoring Screen by pressing P from the FRS Main Screen. Analyze the regi ster and status information provided to help determine the cause of the problem.

2-30 Server Cards

Model No.

Running Head

ACS-FRS Card Troubleshooting FRS Card

5. Go to the Circuits Screen of the FRS card (which can be accessed by selecting Circ from the FRS Main Screen). Verify that the affected circuit STATUS is up (indicated by a “U”). If it is not up, this may indicate that an LMI is down in the far end of the circuit. Highlight the affected circuit and type P and the performance registers for the circuit will appear . Anal yze the information p rovided to help deter mine the cause of t he problem.

6. Loopbacks are availabl e on the “C” ports only . If a “C” port wit h an LMI is looped back toward itself, the PORT TYPE must be nni for the loopback to function.

7. If the FRS card is determined to be faulty, replace it and return the faulty unit for repair to the location specified by your distributor.

3.1 Introduction

This chapter provides installation, configuration, and troubleshooting information for the Management Channel Concentrator (MCC) card.

Note that this card is labeled as an ACS card on its faceplate ejector, and it is called an ACS-MCC card only in the user interface screens described in this chapter. Throughout this chapter, it is referr ed to as the ACS-MCC card.

3.2 ACS-MCC Card Descriptions

3.2.1 ACS-MCC Card Description (881360)

The ACS-MCC card uses 631xx MCC firmware a nd allows you to manage remot e Integ rated Access Systems by using TCP/IP or SNMP/UDP/IP communication protocols. The control link to each remote sy stem can be the FDL ( Facility Data Link) bits of an ESF- framed T1 line. Or, for an E1 line, this link can use the S

A4 bits in the frame alignment words of th e E1 signal.

Full time slot B7R requires a DACSII 6.1 or equivalent . MCC doesn’t talk direct to FDL li nk,

this requires a DACs to convert full timeslo t B7R to B4R.

The ACS-MCC card incorpora te s f our Muni ch32 chi ps (t wo on the main board and t wo on a daughterboard). which allow up to 128 WAN interfaces. The ACS-MCC card also supports three configurable high-speed ports (C1, C2, and C3), plus an Ethernet 10Base-T port for LAN routing management.

The MCC can route IP datagrams between all of its interfaces, based on each datagrams IP destination address . Datagrams are directed (or routed) to the interfa ce carrying the sub-net to which the datagram belongs or is being trans ported to, ac cording to th e conten t of the routing table. The routing table may be supplied with dynamic routes from the Routing Information Protocol (RIP) when enabl ed. If no matc h is found in the routin g table , a defaul t ro ute can be designated to direct all unresolved datagrams to a specific interface.

Figure 3-1 shows the role of the ACS-MCC card in a Network Management System. Both SNMP alarm traps and TELNET configur ations run over this path. They can use the FDL (T1 line), the S

A4 bit of the frame alignment word (E1 l ine ), or a ful l DS0 ti me sl ot of a T1 or E1

line.

ACS-MCC Card Descriptions MCC Card

The FDL is a 4 kbps channel that uses every other framing bit of the T1 extended super frames. When the FDL is used for remote system control via TCP/IP, T1 performance stat istics are not gathered.

The S

A4 bit of the E1 frame alignme nt word is the first bit of time sl ot 0 of each frame. This

bit is called the national bit; it also comp rises a 4 kbps data channel.

Figure 3-1.Typical MCC Application

If the FDL is used to transmit and receive information, a DACSII (6.1 or higher) must be used to convert the FDL/IP information into DS0. On point-to-point circuits, the DACSII is not needed. The MCC can also be used t o create l arg er "trees" in which the high-spee d ports (C1, C2, and C3) can interconnect the different ACS-MCC cards in the hierarchy.

3.2.1.1 Jumper/Switch Settings

The ACS-MCC card does not have any jumpers or switch settings.

3.2.1.2 Installing the Card

Insert the ACS-MCC card into one of the server card chassis slots (P1 to P3). The system can accommodate up to three server cards.

ST ATE

The State setting determines whether the port is active or inactive. Set the State to stdby (standby) to disable the Ethernet port, or choose actv (active) to enable the po r t.

IPADDR

When configured for unnumbered interfaces, the IP Address setting identifies the global IP Address of the MCC. This address is thus valid regardless of the state of the Ethernet port. When configured for numbere d interface s, the IP addres s of the Ether net port iden tifies the IP address of the Ethernet interface only.

NETMASK

The IPADDR together with the NETMASK ide ntifies the IP network for the Ethernet interface. Any valid netmask address is acceptable.

DEF RT

The Default Route setting identifies the IP Address of the port used to forward IP datagrams with destination unknown to the MCC. When stat (static) is selected, the IP add r ess must be entered by the user. When dyn (dynamic) is selected, the IP address is dynamically assigned by a router. RIP must be turned on if dyn is selected. The default is none.

RIP

When the Routing Info rmation Proto col (RIP) sett ing is off (de fault), no RIP t raffic i s allowed into or out of the Ethernet interface. Setting this variable to rx allows incoming RIP traffic only, while setting it to tx allows onl y outgoing RIP traffic. Setting this variable to rx/tx allows both incoming and outgoing RIP traffic.

Note: Due to the high number of interfaces on the ACS-MCC card and the relatively low

bandwidth of the Munich interfaces, you should be careful when implementing the RIP option.

When the Split Horizon (SH) variable is set to on, the ACS-MCC card does not automatically send RIP information along routes it "learned" through the same interface. The default is off.

WEIGHT

The Weight parameter assigns a weighting variable to the specified interface. The number must be between 1 and 15. The default is 1.

FMT-MAIN

This parameter is used to indicate the forma t of the 64 ports on the main board. When bxr is selected, ports 1 through 64 are configur ed to B4R (E1) or B7R (T1). When hdlc is selected, ports 1 through 64 are configured to 64 kbps. (See note below for exception.)

FMT-SUB

This parameter is used to indicate the format of the 64 ports on the sub-board. When bxr is selected, ports 65 through 128 are configured to B4R (E1) or B7R (T1). When hdlc is selected, ports 65 through 128 are configured to 64 kbps. (See note below for exception.)

Note: The only invalid configuration for FMT- MAIN and FMT-SUB occurs when

FMT-MAIN = bxr and FMT-SUB = hdlc. This configuration is not supported.

IF-TYPE

The IF-TYPE parameter determines the IP addressing scheme to be used by all interfaces (except the Ethernet interface, which is always numbered). The default option is unnum, which causes the interfaces to be unnumbered. When configured in this manner, the MCC is addressed through th e global IP addre ss of the Ethernet interface, regard less of the orig inating interface, and t he IP address of all in ter fa ces (except the Ether ne t i nterface) is dete rmin ed by the interface on the remote e nd. Selecti ng unnum may help conse rve IP addre ss, but may no t be compliant with the HP OpenView network management system.

The num option al lows for numbered in ter fa ce s. W hen t h is op ti on is selected, each i nterface is assigned a local IP address on the same net wo rk as (but di fferent from) the remote device. Two broadcast IP addresses are also reserved for each interface, for a total of four IP addresses per port. Numbered interfaces are industry-standard, and are compliant with the HP OpenView network management system.

FORMAT

The Format setting determines the format of the information received from the remote system unit. For the numbered ports (1-128), the options are b7r (for T1 links) and b4r (f or E1 links). For ports C1-C3, the opti ons are hdlc (hi gh-le vel dat a link contro l) and fr (frame relay). If fr is selected, the user must select a DLCI (data link connection identifier), which corresponds to the virtual circuit number of the frame relay destination address. When more than one TS is selected, the MTU is 1,500. The i nternal MTU is expanded by f our on the WAN segment to allow 1,500 byte frames to pass with the addition of the frame relay header without fragmentation. When fr is selected, more than one TS must be allocated.

RIP

When the Routing Infor mation Protoc ol (RIP) setti ng is off (def ault), no RIP tr affic is allowed into or out of the Ethernet interface. Setting this variab le to rx allows incoming RIP traffic only , while setting it to tx allows only outgoing RIP traf fic. Setting this variable to rx/tx allows both incoming and outgoing RIP traffic.

Note: Due to the high number of interfaces on the ACS-MCC card and the relatively low

bandwidth of the Muni ch int erfac es, th e user should be cauti ous abou t imple ment ing the RIP option, as there is a substantial risk of broadcast storms causing congestion in the netw ork.

When the Split Horizon (SH) variable is set to on, the ACS-MCC card does not automatically send RIP information along routes it "learned" through the same interface. The default is off.

WEIGHT

The Weight parameter assigns a weighti ng variable to the specified i nterface. The number must be between 1 and 15. The default is 1.

Refer to Appendix B in the System Reference Guide for further information on Error Messages reg arding this card.

3.6 ACS-MCC Card Troubleshooting

MCC card problems could indicate a number of possible causes, including:

• Misconfigure d IP parameter at th e far end

• Faulty cabling between the MCC LAN port and the LAN

• T1 or E1 network failure

• Improper network configuration

• Improper MCC card configuration

Typically, a problem is indicated by the inability to route IP traffic to/from or through the MCC card. You can perform numerous tasks to isolate the trouble and clear it. When troubleshooting problems on IP communications through an MCC card, follow this general sequence:

1. If all IP traffi c is af fe cte d, verif y that t he US/EUR jumper is corre ctly pl aced to match the US/EUR jumper on the chassis. The MCC card performs a self-test on power-up. A “healthy” card will have a green LED lit on the front panel. Do not proceed with further steps until a green LED is present.

2. V erify that the Ethernet Port (E) is actv and that the corr ect I P addr es s ( IPADDR) and NETMASK have been entered. At this point, attempt to “ping” (from the CPU card TCP/IP screen) the IP address of the MCC Ethernet port from another device on the LAN. Pressing N from this screen will display the Network Statistic registers for t he Ethernet port. Analyze the information to determine the cause of the failure. Do not proceed with further steps until this ping is successful.

3. From the CPU Main Menu screen, go to the TCP/IP screen by pressing I. Verify that the option s and addresses on the TCP/IP screen are correct. Press “P” (for ping) and enter the IP address of the MCC card Ethernet port.

4. If Step 3 is not success ful , ver if y tha t th e DEFAULT IP PORT is set to serv and that the DEF AULT IP SLOT is set to the chassis slot in which the MCC card resides (P1, P2, or P3). At this point, attempt to pi ng t he card again by pressing P. Do not proceed until this ping is successful.

5. V eri fy that the T1 or E1 network is wo rking properly by checking f or current CGA-Red and CGA-Yellow alarms. If no CGA alarms are present that would affect IP traffic, continue w ith step 6.

MCC Card ACS-MCC Card Troubleshooting

6. Verify the configuration settings for the affected MCC port. Be sure the port is

connected to the proper WAN card and port, that t he correc t FORMAT is selected and that the appropri ate IP address (IPADDR) and NETMASK have been entered. If these assignments appear corr ect, go bac k to the CPU TCP/IP menu and ping th e addres s of the remote device connected to that MCC port. If this is not successful, ping back toward the MC C card from the remote device. Pressing N from the MCC card Port screen will display the Network Statistic registers for the port. Analyze the information to help determine the caus e of the failure. The problem may be either in the network between the MCC port and th e remote device , or incorrect IP addressin g/configura tion of the remote device.

7. If the MCC card i s determined to b e faulty , replace it and return the faulty unit f or repair to the location specified by your distributor.

ATM Card Introduction

Chapter 4 ATM Card

4.1 Introduction

This chapter provides installation, configuration, and troubleshooting information for the

Asynchronous Transfer Mode (ATM) Server Card.

With ATM firmware (641xx) the ATM Concentrator is an application running on the Advanced Communications Server (ACS), providing a DS3 ATM port. It supports both constant bit rate and variable bit rate applications and offers connectivity from WAN, HSU analog voice, FRAD and BRI. Note that this card is labeled as an ACS card on its faceplate ejector. It is called an ATM card only in the user interface screens described in this chapter. Throughout this chapter, it is referred to as the ACS-ATM card.

The acceleration in ATM deployment has created an opportunity for users to migrate legacy applications to both the private ATM backbone and to public ATM services. The incentives for integrating the existing applications with the typically higher-speed ATM traffic are primarily financial in nature, but another significant benefit is the resultant streamlining

network operations and management.

4.2 ACS-ATM Card Descriptions

4.2.1 ACS-ATM Card Description (882060)

The ACS-ATM card is a high-performance server card designed to concentrate the entire bandwidth of the Inte grated Access Syste m into a high-speed ATM link. The input to this car d is derived from W AN T1 and/or E1 interfaces, from any of the user cards in the system’s eight chassis user slots and an 10-Base-T ethernet port for wirespeed LAN extension. All existing user interfaces are supported, including voice and data.

The card currently suppor ts ATM Segmentation and Reassembly (SAR) process or and a DS3 electrical interface (BNC connectors). In this release, only the UNI is supported. The ACS-ATM card circuitry is capable of supporting ATM Adaptation Layers AAL0, AAL1, AAL3, AAL4, and AAL5.

The ACS-ATM card connects a wide range of equipment to an ATM network, including analog PBX/key systems, digital PBXs, low-speed data terminal equipment, N x 56/64 kbps data terminal equipment, and video codecs.

ACS-ATM Card Descriptions ATM Card

The ACS-ATM card consists of a main board and sub-module card. The main board is a variation of the existing Advanced Communication Server (ACS). The sub-module card handles all ATM functionality’s, including the Physical Layer, ATM Layer, and Adaptation Layer. ATM connectivity is provided to and from the following system cards:

• WAN (all card types)

• HSU (all card types)

• FXS, FXO, FXS-C, FXO-C

• E&M (all card types)

• BRI (U*8 and SC cards only)

• FRAD 232*10

Incoming traffic is directed through the internal bus system to the ACS-ATM card, which provides adaptation and encapsulation. The ATM output in the first release of the product is an electrical DS3. Typically, the ATM connection is a local ATM switch which multiplexes virtual circuits or iginating from the IMACS with oth er high-speed traf fic. The ACS-A TM ca rd is capable of handling both Variable Bit Rate and Constant Bit Rate Applications.

4.2.1.1 Card Jumpers/Switch Settings

The ACS-ATM card does not have any jumpers or switches on its mainboard.

4.3.6 Variable Bit Rate (VBR) Configuration Screen

The ACS-ATM card supports fou r super -rate channels up to 2.0 48 Mbps each. The aggregate bandwidth cannot exceed 4.096 Mbps.

Additionally, the card is capable of supporting up to 64 HDLC channels operating at Nx64 kbps (N = 1 to 32). The other 64 channels are accessed by using the “gre at er than” (>) and “less than” (<) symbols. The tot al HDLC bandwidth availa ble for va riabl e-bit -rat e (AAL 3/4 & 5) traffic on a single ATM Server is 8 Mbps.

Alternatively, only C1can be used as an Ethe rne t cont roller. The ACS-ATM card is equipped with a single 10base-T Et hernet connect or. In addi tion t o the 8 Mbps of VBR tra f fic f rom the HDLC controllers, the Ethernet port provides encaps ula ti on f or Et her net MAC la yer fra mes.

PEAK (Kbps)

The Peak Bandwidth se tting determin es the maximum bandwid th (in kbps) use d by the source port in the direction of the ATM virtual connection. If wan is chosen in the Legacy selection above, the value is the product of the time slot setting multiplied by the rate setting (e.g., 5 time slots x 64 k rate = 320 kbps ) and is automati cally calculat ed. In wan mode, the user cannot change this parameter, which appears as n/a. Same if legacy is user card.

If lan is used in the Legacy selection, the user must select the appropriate peak bandwidth. Valid selections are 1 to 10000.

MEAN (Kbps)

The Mean Bandwidth setti ng determines the ave rag e b andwi dt h (in kbps) used by t he sour ce port in the direction of the ATM virtual connection. If wan is chosen in the LEGACY parameter, the value is the product of the number of time slots selected in the TS parameter multiplied by the value of the RATE parameter. (For instance, eight time slots x 64K rate = 512 kbps.) This value is cal culat ed automa tical ly. Can me modified from 1 to calculate value.
