Ok, linecard in the GSR are :

POP1-R1:
SLOT 1  (RP/LC 1 ): 1 Port ISE Packet Over SONET OC-48c/STM-16 Single 
Mode/SR SC connector
L3 Engine: 3 - ISE OC48 (2.5 Gbps)
SLOT 5  (RP/LC 5 ): 1 Port ISE Packet Over SONET OC-48c/STM-16 Single 
Mode/SR SC connector
L3 Engine: 3 - ISE OC48 (2.5 Gbps)

POP1-R2
SLOT 1  (RP/LC 1 ): 1 Port ISE Packet Over SONET OC-48c/STM-16 Single 
Mode/SR SC connector
L3 Engine: 3 - ISE OC48 (2.5 Gbps)
SLOT 5  (RP/LC 5 ): 1 Port ISE Packet Over SONET OC-48c/STM-16 Single 
Mode/SR SC connector
L3 Engine: 3 - ISE OC48 (2.5 Gbps)

POP2-R1
SLOT 4  (RP/LC 4 ): 1 Port ISE Packet Over SONET OC-48c/STM-16 Single 
Mode/SR SC connector
L3 Engine: 3 - ISE OC48 (2.5 Gbps)
SLOT 6  (RP/LC 6 ): 1 Port ISE Packet Over SONET OC-48c/STM-16 Single 
Mode/LR SC connector
L3 Engine: 3 - ISE OC48 (2.5 Gbps)

POP2-R2
SLOT 4  (RP/LC 4 ): 1 Port ISE Packet Over SONET OC-48c/STM-16 Single 
Mode/SR SC connector
L3 Engine: 3 - ISE OC48 (2.5 Gbps)
SLOT 6  (RP/LC 6 ): 1 Port ISE Packet Over SONET OC-48c/STM-16 Single 
Mode/LR SC connector
L3 Engine: 3 - ISE OC48 (2.5 Gbps)

All LC have 512MB RP memory and 512MB Packet memory.

Juniper router, ERX-1440, interconnect adsl user with our ip backbone. They 
are connected on a pair of  Catalyst 6509 with MSFC2 connected to
another pair of gsr connected to pop1-r1 e pop2-r2:

ERX --- SW1-----BR1----POP1R1===========POP2R1
 |                |              |            |
  --------SW2-----BR2----POP1R2===========POP2R2
