[j-nsp] Juniper T1 Cross Connect M40

[Erik Sundberg]

Hello,

We have a juniper m40 and we are tring to setup a cross connect between 2
t1, (cisco-hdlc). The t1's come in to the m40 by a Channelized ds3. I am
looking on juniper site for some examples and reading up on it. just wonder
if anyone has tried this and if there is anything to watch out for??

And if anyone would be so kind to send me a example of a t1 cross-connect
using Cisco hdlc that would be greatly appreciative.

Layout
------
customer router
t1 line
M13 Mux
channelized ds3
m40 crossconnect
channelized ds3
m13 mux
t1

Thanks

Erik

I am also interested in this. Can the Juniper M40 act like a
Eastern Research (aka Lucent DACS)? As in cross connecting
DS0s, DS1s, and DS3s (STS1s).

This would be for the t1, DS3, and Sonet interfaces.

Can it carry voice calls in other words?

Thank you for your time,

matt

Juniper routers are not TDM switches. A Juniper router can cross connect
between interfaces, but does so on a *packet* basis. We use it (for
various reasons) to cross connect between Ethernet VLANs, e.g.

interfaces {
ge-3/0/0 {
stacked-vlan-tagging;
encapsulation flexible-ethernet-services;
unit 1129 {
vlan-tags outer 1579 inner 2650;
encapsulation vlan-ccc;
}
unit 1130 {
vlan-tags outer 1058 inner 2650;
encapsulation vlan-ccc;
}
}
}

protocols {
connections {
interface-switch VC36129700 {
interface ge-3/0/0.1129;
interface ge-3/0/0.1130;
}
}
}

Well here is the final config for the t1 cisco-hdlc-ccc cross connect. I had
a couple of people ask me to post it after I got it working.

interfaces {
t1-0/1/0:11 {
encapsulation cisco-hdlc-ccc;
unit 0 {
family ccc;
}
}
t1-0/1/2:5 {
encapsulation cisco-hdlc-ccc;
unit 0 {
family ccc;
}
}
}
protocols {
mpls {
interface t1-0/1/0:11.0;
interface t1-0/1/2:5.0;
}
connections {
interface-switch Customer1 {
interface t1-0/1/0:11.0;
interface t1-0/1/2:5.0;
}
}
}

you need to enable mpls on the interfaces it wouldn't commit the config
without it.

Here is how to check the status of it

user at router> show connections
CCC and TCC connections [Link Monitoring On]
Legend for status (St) Legend for connection types
UN -- uninitialized if-sw: interface switching
NP -- not present rmt-if: remote interface switching
WE -- wrong encapsulation lsp-sw: LSP switching
DS -- disabled tx-p2mp-sw: transmit P2MP switching
Dn -- down rx-p2mp-sw: receive P2MP switching
-> -- only outbound conn is up
<- -- only inbound conn is up Legend for circuit types
Up -- operational intf -- interface
RmtDn -- remote CCC down tlsp -- transmit LSP
Restart -- restarting rlsp -- receive LSP


Connection/Circuit Type St Time last up # Up
trans
Customer1 if-sw Up Aug 13 16:42:31

t1-0/1/0:11.0 intf Up
t1-0/1/2:5.0 intf Up
